RE: [PHP] Can I use Microsoft Access as a database?
First you have to define a *system* data source (DSN) with the ODBC control panel applet - e.h. with the name "accessdb". Be sure, that *other* applications are able to use this data source as well, before you try to access via PHP (e.g. with Excel, which comes with a data query tool to import data from ODBC data sources or MSQUERY). Then you open the connection as follows, *without* user or pw: The error "Data source name not found and not default..." means, that the name of the given data source was not found in the system DSNs. It has to be a system DSN, because PHP runs within another user context (e.h. IUSR_... if you use PHP and IIS or the System Account, if you use PHP and Apache), which does not have the *user* DSNs, which you as a user defined for yourself.

Cat, the other other white meat

On my Windows I see the same thing - "Configuration File (php.ini) Path"
points to C:\WINDOWS (even though there is no php.ini there) and "Loaded
Configuration File" points to the dir where the php.ini actuall is. My setup
(PHP 5.2.6) works fine. Presume you did restart apache after making the
change? It looks like your php is using your php.ini since phpinfo reports
(none) when you rename it. Is there anything in your phpinfo output that
relates to your php.ini? Maybe some error near the beginning of php.ini
causes php to stop loading the ini file? Check that the "extension_dir" in
phpinfo agrees with the "extension_dir" in your php.ini.
Maybe try enabling error logging in the php.ini and check the log file - I
use apache\logs\phperror.log and invalid extension loading is definitely
reported there (I've had this problem before). In php.ini set
"log_errors=On" and set "error_log=c:\apache\logs\phperror.log" (or wherever
your apache is installed). Restart apache and check the phperror.log file.
If you find nothing then create a dummy entry to force an error, something
like "extension=php_dummy.dll" to check that the error logging is working.
If your logging is working and there is no error reported for loading the
mysql extension, and you still see no entry for mysql in phpinfo output,
then you have a different problem, maybe a mysql installation problem.

That's it, i think. I've enabled display_startup_errors and now on start apache i receive errors. PHP can't find libraries of MySQL extensions.

RE: [PHP] Obeying the rules (was Simple login form with cookies)
I'm sure those who've been on this list a while muttered "here we go again..." when this thread started. Personally I think if there was a poll about this the bell curve would have some on the left demanding we all top post, many on the right of the curve demanding we all bottom post, and a solid bulge in the middle representing the great unwashed "couldn't give a damn" folks (and probably "couldn't give a damn" to enter the debate). On the very few occasions I've had anything to contribute I've generally bottom posted, mostly because I've seen this debate before and partly because I think it's easier for some people, but I'd place myself in the middle of the bell curve. I think most people on this list are more than smart enough to quickly figure out the thread in a post regardless whether the previous person top posted or not. Most of the regular responders bottom post which makes up the bulk, but I think if you look at the variety of people who post it's about 50/50, and most times it doesn't cause any problem at all. I agree that rules are important, but some are more important than others, and I think the top-posting rule is pretty low in the list of priorities, more a useful guide than a rule. Things like personal attacks and attempted mail spoofing are more important - both happened during the course of this thread but hardly raised an eyebrow. I also agree that context plays a big part, because once a thread starts getting complicated with many responses then bottom posting definitely makes it easier to follow, but most threads don't get to that stage.

It might be easier to understand if you don't use the same var names:
function foo(&$arg) {
$arg = 42;
unset($arg);
$arg = 'meaning';
}
$a = 0;
foo($a);
print("$a\n");
-Shawn
--
Another way to see it (from Shawn's example): the "&" is an "address of"
(reference to) a variable, so function foo(&$arg) creates a local variable
$arg pointing to a global variable called $a. Changing the value of local
$arg updates the global $a. The unset($arg) removes the local $arg but has
no effect on global $a. The next line $arg = 'meaning' creates a new local
variable called $arg which has no connection whatsoever with the $arg that
was unset - it could just as well have been called $xyz.
As Shawn pointed out there's no problem here with scope, you were just
confusing yourself by using the same variable name in the function, but it's
a separate local variable regardless of what name you give it.
A slight variation of your example:
You get exactly the same result as your example, for the same reason, the
only difference is that you obviously can't change the local variable name
in the function.
A final variation (to drive the point home):
function foo(&$arg) {
global $a;
$a = 42;<== at this point $arg = 42
unset($a);
$a = 'meaning'; <== $arg is still 42
$a = &$arg; <== $a now points to same address $arg is pointing to
$a = 'of life'; <== $arg now = 'of life'
}
$a = 0;
foo($a);
print("$a\n"); <== prints 'of life'
Here in function foo() local $arg and local $a are both pointing to the
global $a, and changing either of them changes the other (and changes the
global variable). After unset($a) only local $arg is pointing to global $a.
After $a = &$arg both local variables are again pointing to global $a, and
local $a value has therefor obviously changed from 'meaning' to 42. Then
after $a = 'of life' both local variables and the global $a is changed to
'of life'. Local $a and global $a have the same names but are different
variables. Also, the local $a after unset($a) happens to have the same name
as the $a before unset($a) but it's a different variable, it could just as
easily been called $b after unset($a).
A final point: the "global $a;" in the function doesn't mean it's THE global
$a, it just means it's a local variable called $a pointing to (referencing)
a global variable with the same name. In PHP it has to be the same name
because that's the way the "global" statement works, but it can sometimes
create the impression that it's the same variable.
Hope I haven't made that as clear as mud.
Cheers
Arno

Thanks, Ash http://www.ashleysheridan.co.uk -- You can open the control file any time you want. The info in the control file tells you whether to proceed. The transfer program adds the entry when the log has been transferred, the processing script updates the entry to indicate it's been processed.

What would happen if you tried to access the control log file whilst it was in the process of being written to? Admittedly, you reduce your chances of failure because there is less data being written to the control log than the actual log, but the chance of reading incomplete data is still there! Thanks, Ash http://www.ashleysheridan.co.uk A control file is used to control processing, a log file is used to log events. I'm definitely talking about a control file. If the control file happens to keep a log then it's a bonus, but not its primary purpose. Access the control file while being written to? I'm talking about a short single-line entry, and the file is only written to when the write command is processed. Copying a file is very different to issuing a single write command. Don't forget that PHP and webservers run on top of operating systems, and the OS ultimately handles all file activity. The OS ensures that another process can't read a file that is halfway through a write command (any computer would instantly crash if that sort of basic housekeeping wasn't done). If you don't trust the OS then file locking can be used (though pointless in this case). For the ultra-paranoids who don't trust OS's or locks you can either (a) choose a different career, or (b) add a time-stamp to the beginning of the entry and check that the entry wasn't written in the last few nanoseconds (if you get this far I'd recommend option a). You can even go so far as to check the length of the timestamp string to be sure that you got all of it, and if it's too short you know you're busy reading a file that's halfway through a write command, and sleep for a millisecond and then try again ;) Cheers Arno -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks, Ash http://www.ashleysheridan.co.uk --- If anyone was left a bit unsure about whether or not a write command in PHP could result in a file on a local filesystem being left in a semi-written state (i.e. some other script started reading the file while your script had only written part of its output string) rest assured that fwrite() always writes *all* the contents to the file without the need of flock(), by the time any other process (whether PHP or not) reads that file (assuming you're not writing megabytes of data with a single fwrite()). To quote the PHP manual: "If handle was fopen()ed in append mode, fwrite()s are atomic (unless the size of string exceeds the filesystem's block size, on some platforms, and as long as the file is on a local filesystem). That is, there is no need to flock() a resource before calling fwrite(); all of the data will be written without interruption."

Thus when having the same web-site open and using SESSION variables but for different users, Internet explorer can become "disorientated". This also "sometimes" happen when I have two separate browsing windows open with Internet Explorer for the same site. I have yet to determine if this is an internet explorer, or PHP or combination of the two that is causing this condition. To my understanding _SESSION variables should be maintained per session, tab or window. If this has been addressed already, my apologies, but thought it worthwhile to mention. If someone perhaps have a solution or can confirm this as a known issue and maybe is the same or related to Angelo's problem? If different browser windows/tabs on the same client-side computer didn't share session info then you'd get the effect of being able to log onto a site with one browser window, but find in a second browser window that you were not yet logged on. Experience will tell you that you're logged on in both browser windows (try it with your online bank). It's not an issue, it's a feature. If you want to be able to use different browser windows as though they were different users then use different browsers e.g. IE and FF on the same client-side computer will look like two separate end users to the server, and they don't share session info or cookies.

If there's a need to ensure that multiple processes don't step on each others toes the file can be locked. The two most common file accesses are read and append, where a lock is mostly not required.

Subject: [PHP] Invoking functions stored in a separate directory?
I am developing an idea for a website engine which can be shared between
several different websites. Each website would have its own directory under
a common root directory, and the engine would be in a separate directory
Engine:
Root
Website_1.com, Website_2.com, Engine
The website directories would each contain the design data for that website,
consisting basically of a mixture of text files and images. The various
pages would be loaded by loading index.php from the website root directory,
and specifying a number of parameters e.g.
http://www.corybas.com/index.php?path=Holidays&level=0&item=0
I have the minimum amount of code in index.php -- just enough to set some
parameters to identify the website, and then include
../Engine/Main_prog.php. This in turn can include any of a large number of
other include files to carry out particular functions.
I have the prototype working nicely on my PC, and on a stand-alone basis on
a server, but now I am trying to upload the multi-website version to a
public host, and am encountering a number of problems, mainly because I have
never done any serious work with UNIX, and the host support staff don't
understand what I am trying to do.
The problems mainly relate to setting permissions to allow the website to
access the engine code. I only have a rough idea of how the permissions
work, but I think that to include engine code the website has to have read
and execute rights to it, and I also think that so far as the engine is
concerned the website will count as 'other'. (I can easily arrange that all
temporary files are written in the website directory.)
I suspect that rather than including the engine code in index.php, it would
be better to call functions in it, so that the website only required
'execute' rights, but I don't know of any way to do this without having
anything running permanently on the server. Can anyone suggest how it can be
done?
-
Using include ../Engine/Main_prog.php won't work for you in a production
environment. You need to create a path.php file that defines the absolute
path to the engine for each website, and include it at the top of your
website script. Then you can do something like:
include ENGINEPATH."Main_prog.php";
You can have different path files, one for dev and one for live, that allows
you to use the same scripts for both environments and just use the
appropriate path definition script.
E.g. Windows path.php
define('ENGINEPATH','../Engine/');
Linux path.php
define('ENGINEPATH','/usr/home/Engine/');
You shouldn't really have permission problems as long as your website and
engine are on the same server. I do something similar where the bulk of my
code is below doc root, and I use path files to find the main system
directories. The beauty of it is you can change your mind about directory
structures, and just change the path file definitions without making any
changes in the application code (my path file defines about 20 directories).
It also lets you do dev on a Windows pc and deploy on a *nix box without any
problems - just use a different path file for each.
One other advantage it will give you for your particualr design is that you
can have multiple engines per server (e.g. Engine1, Engine2, etc) so that
you can bring one engine down for upgrade while still keeping sites running
on the other engines.

Thanks, Ash http://www.ashleysheridan.co.uk - Ash, from what I've seen you enjoy "engaging" in a debate. Well here's something you'll no doubt want to engage in: the number of people who have javascript switched off vs the number of people using browsers that support all the latest ajax-type gizmos. I've not seen anyone told not to go the ajax route, but it's amazing how concerned some people are about whether javascript is switched on or not (the fact that js is required for ajax seems to be overlooked). When w3schools was still keeping stats about it they showed about 5% of users had js switched off (though they conceded the stats were unreliable - tech types go to w3schools and they're much more likely to mess with browser settings than the average user). Generally it's accepted that the average joe doesn't know how to switch js off, or even why they would want to. When we investigated sites where this is specifically measured (e.g. a banking site, which I once worked on) users who had js switched off were prompted to switch it on, and logs showed that 100% of those users reloaded the page with js switched on (and our stats, during the launch phase, showed much less than .5% users had js switched off in the first place). Generally we found that requiring js was a complete non-issue. I've subsequently found this is true on other sites I've worked on, even when users are not prompted. With navigation menus using js more frequently these days and the increased use of ajax, browsing with js switched off is almost not an option anymore. I'm sure, Ash, you'll tell me how corporate firewalls strip javascripts - I'd be interested if you can point out an example and show how common this is. And as for "most people" telling you js is a bad idea - is this true? Do you have stats to back up your statement, or are you just stating your perception as a fact? A second point, Ash, is that you yourself have mentioned coding javascript, and have suggested the use of ajax as a solution to others - I presume you know what the "j" in ajax is? I've even seen you providing javascript solutions without any concern as to whether js was switched on or not. Perhaps your concern about js is selectively applied to certain posts rather than real-world situations? BTW I'm not in a debating mood - I've made my point, no doubt Ash you'll make yours, and I'll leave it at that. But if anyone else has any further info regarding real-world stats or experience about js switched on or off it would be very interesting to hear.

Subject: [PHP] Beginner question
I am trying to use PHP on my web site I am developing now. I have installed
Apache 2.2 and PHP 5.2. My problem is that I can execute PHP code embedded
in my HTML code, but I can't execute the same cose when I put it into a
separate .php file that i then call from within the html code. for example:
I have a html file with

When I take out the php code and put it inot a file pp.php, and I call that
file with my browser ("localhost/pp.php"), it works, too.
But when I change the html code to:
I get a blank page. this is probably something really stupid, but I have
been wrecking my head for days now, and I can't figure it out. anybody has
an idea?
--
I presume your html/php code is in a file with a .php extension? If not then
change the extension to "php" because most other webservers won't parse php
code in a html file. If you have a .php file you can mix html and php the
way you described, and you can put your php code between the
tags.
The php script you're trying to include in your html code with javascript
would presumably echo out the javascript code that ends up in your html
page, but if you don't know php then you're trying to run before you can
walk.
If possible try to see what javascript code is being generated (echoed) by
the php script and put it in a normal .js file (e.g. pp.js) and then use it
like any other javascript file
This isn't always possible because often php is used to decide what
javascript to output (otherwise why bother). If you have to use php to
generate your javascript code then start with small steps - try echoing some
simple js code in your pp.php (like an alert) just so you can see how it
works. Once you get that working you can move on to more useful things.
To illustrate, what's actually happening with the code you have at the
moment is this:
The browser parses the initial html code and finds
And sends a request back to the server for pp.php
The server runs pp.php and send the output generated by the php script back
to the browser,
so effectively the browser ends up with
Printing with php
Obviously that isn't going to work. Hopefully you can now see what the
problem is and how to fix it.

You and someone else told me that. I am glad that you did because that is exactly what the problem was. Thanks for being patient and understanding. Scott -- Sure, all part of the learning experience. Understanding why you can view an html file in a browser but not a php file is essential: when viewing an html file, it's the browser (client-side) that's processing and rendering the html code, but the browser can't process php code. For that you need the webserver (server-side). Browsers are built to understand and process html and javascript, but only a webserver can understand and process php script. Unless you're developing or learning, the browser and the webserver are almost always on different machines (that's the whole point of the internet!). In your case (and most cases) the webserver is Apache. Apache treats html files and php files differently. In the case of html files it just gets the file and sends it back to the browser, as it was requested to do. But in the case of php files it opens the file and starts processing it, i.e. running it as a program. Apache processes (runs) the php script which generates the html script, which Apache then sends back to the browser. The browser then processes that html script and displays the result. It's basically the same concept for all server-side scripting. When you type http:// in the browser address bar, you're telling the browser to communicate with a webserver, using the hypertext protocol. When you type file:// in the browser address bar, you're telling the browser to communicate with your local file system. Try http://local-directory/file.html and you'll see it won't work, whereas file://local-directory/file.html will work just fine (assuming you've got file.html in local-directory).

Subject: [PHP] using return in include files
I'm trying to figure out what the desired behavior is of using the
return function to bail out of an include page.
I did some testing, and this is what I concluded.
First, I created the following file:
";
?>
I then called it as follows:
include('test.php');
include('test.php');
include('test.php');
The output is:
blah blah blah blah
Second, I changed the test.php file to be the following:
";
function myFunc($test) {
}
?>
When I load the page now, it throws the following error: PHP Fatal
error: Cannot redeclare myfunc()
It appears that if there are functions in the include page that you
can't use return to bail out. What is the desired functionality in this
case? Is this a bug in how php handles it? or was return never designed
to be used this way?
Any thoughts are appreciated.

Include works as though the "include" statement line is replaced by the code
that is being included. So try the following exercise and it should become
obvious why you're getting that error: copy-and-paste the code from test.php
into the code that "includes" test.php for each line that includes test.php,
and then delete each of those include lines (I'll comment them out). You end
up with:
";
function myFunc($test) {
}
// include('test.php');
if (defined('TEST_LOADED')) {
return;
}
define('TEST_LOADED',true);
echo "blah blah blah blah";
function myFunc($test) {
}
// include('test.php');
if (defined('TEST_LOADED')) {
return;
}
define('TEST_LOADED',true);
echo "blah blah blah blah";
function myFunc($test) {
}
?>
Run that and you should get exactly the same error. Interestingly under php4
neither your code nor my expanded version of your code throws an error, so I
assume you're using php5?
If you're trying to avoid including the file more than once you could use
"include_once", but I've had problems with that - the file was previously
included but not in the same scope, so it wasn't included second time it was
called and yet none of the included file's contents existed. The way I got
round it was by assigning a value in the include file, and then testing for
that value before including the file.
For example:
test.php

You can't use a define for this because it has a much wider scope and you
end up with the same problem as using "include_once".

[PHP] Data Types Problem
Hi Guys
I seem to have a problem with data types in php
when executing the following script , i do not get the desired output.
i a pass url parameter (message) to the script.
if i pass a numeric value (1) , the script accepts it as '01' and vice
versa.
the same with 0 and '00'
here is the script:
echo "theMessage : '" . $theMessage . "'\n";
if ($theMessage == "01")
{
echo "message : '01'";
}else if ($theMessage == "00")
{
echo "message : '00'";
}else if (is_numeric($theMessage))
{
echo "Numeric Input : " . $theMessage;
}else
{
echo "Invalid Input";
}
?>
i presume that i am not interpreting the data types it should be
interpreted.
can anyone please help

[PHP] Newline and tab characters
I've just noticed that "\r\n" and "\t" characters create a space when rendered in the browser (tested in IE and Firefox). I'd always thought the browser would ignore these characters. This wouldn't normally be a problem but the wysiwyg html editor in the cms I'm using tries to be friendly by formatting the html code, so something like getonline becomes \r\n\t\tget\r\n\t\tonline and instead of being displayed as getonline it's displayed as get online. Is there a simple way to sort this out or do I need to create a function to strip these characters before display, checking first that they don't occur within a tag in which case I mustn't strip them.

So it's not at all true that Apache "simply ignores the 80% or so that use Windows". You previously said you're new to php, so what are the chances that this has more to do with your own inexperience with php rather than some Windows-only bug you've discovered and are revealing to the rest of the php community? The error message mentions the script name and a line number, have you checked what code is causing the error? You said you installed php 5.3 on your pc. Chances are very high that the host you uploaded this to is not running php 5.3. Someone previously mentioned that there are differences between 5.3 and the previous versions that could account for your issues. Have you tried installing php 5.2 and trying it again? There are also settings in php ini file that you can change to change the error reporting, but it's not clear if you've tried that yet. One final thing, have you tried to google with the error message to see how others dealt with this problem?

is header('Location xxx').
I have used header to redirect users from pages, and kinda used it alot. i
know about the whitespace causing warning, but most of the pages i'm sending
users got html and php mixed so i'm confused about how to remove whitespace
in a html/php file. the error is :
Warning: Cannot modify header information - headers already sent by

if($valid)
{
$msg='111';
$user->dbupdate();
header("Location: /admin/index.php?msg=$msg");
}
else
{
foreach($errors as $val)
echo ''.$val.'';
}
and on admin index i get $msg and display it.

//lots of stuff

break;
case '421':...
}
?>
// more html and php
how can i fix this?
--
It's possible that on your localhost you have output_buffering set on either
in php.ini or in a .htaccess, which would avoid the displayed error about
headers. If it's switched on locally and off for your host server then
you'll get the problem you reported. Check that this is off locally (use
phpinfo) so that you can be sure your code is working properly before you
upload.
Alternatively if you want to be able to do a redirect after you've already
started your output (this is sometimes done for error handling) you could
use ob_start() to start output buffering, ob_end_clean() to clear the output
buffer and start again, and ob_flush() to send the output buffer. If you
want to continue using output buffering after an ob_end_clean() you'll have
to do an ob_start() again.

Changing register_globals in script will not have the desired effect, since
the action of registering globals will have been either completed or skipped
by the time you call ini_set(). If the host allows it, you can override it
in .htaccess, but I've not been able to do so on the couple sites I've
touched that were hosted on by a shared hosting provider. In those cases, I
WAS able to create my own php.ini file in the web root folder and configure
it as needed. Of course, if you do that you should also configure Apache to
not serve that file if requested.
Andrew

You're right, you can't change register_globals in script but you can query
it in script, which is what I was referring to. There aren't many settings
you can change in script, about the only useful one that we use is
max_execution_time. Either way, what I find in testing is that on our host
php returns the value reported in phpinfo as the "local value" which is
correct, because that's the value that should be in effect (combination of
httpd.conf, php.ini, .htaccess and values set in script), but the value
that's actually in effect is the master value.
For example, if php.ini sets register_globals on and .htaccess sets
register_globals off, then the code
ini_get('register_globals')
reports register_globals is off (it's reporting the local value) but in fact
register_globals is on. In this particular case our app would stop with a
configuration error if it found register_globals on, but it thinks it's off
so happily carries on.
Local is supposed to override master values but they have master overriding
local values. I'm trying to confirm that local is supposed to override
master, and find a proper reference that I can show to my hosting guys. I
searched php.net but they don't mention which one takes precedence. Anyone
know of any references?
BTW Andrew, were those hosting servers that wouldn't allow override in
.htaccess running FastCGI? Maybe FastCGI doesn't allow config settings in
.htaccess but I can't find anything conclusive about that either.

RE: [PHP] Fixing the path

I have always used the DOCUMENT_ROOT for my includes, but the other day I installed the application in a subdirectory, and as you've guessed a lot of the includes didn't work. I have been reading up on the subject of absolute vs. relative paths etc. And on the subject of defining your own document root. I need the application to be as user friendly as possible, and I would like to avoid having users enter path details in the configuration. What is the best way to solve this problem? Rico. -- Who are your users? Can users download the script and run it on their own servers? If so there shouldn't be a problem asking them to set a path in a config file because presumably the users would know something about servers and paths, and presumably they'll know enough to create the directory and copy the files there in the first place. If you have an install process you can pick up the current directory from system globals and write it to the path setting in the config file.

[PHP] Output buffering
Has there been a change to the way output buffering works?
The manual states for ob_get_contents()
"This will return the contents of the output buffer or FALSE, if output
buffering isn't active."
But the following works in php4.4.4 and php5.2.6 whether output buffering is
on or not
";
echo "output_buffering is ";
echo ini_get('output_buffering')?"on":"off";
echo "";
$check = ob_get_contents();
if ($check === FALSE)
echo " FALSE";
$info = ob_get_contents();
ob_clean();
echo $info." -2-";
ob_flush();
?>
The output is "output_buffering is off -2-" (or on) displayed once - "FALSE"
is obviously never appended.
According to the manual I shouldn't see anything at all when
output_buffering is off (or if memory serves me correctly I should see an
error about "headers already sent" or something). Looking at phpinfo
confirms the value echoed by the script. Has something changed with output
buffering?

Use
echo ob_get_level() . "";
to find out how many levels of output buffering you are wrapped in.
Whether output buffering is set to start automatically, and whether output
buffering is on right now are two different things:
ob_end_clean();
echo ob_get_level() . "";
echo ini_get('output_buffering') . "";
--
Thanks David. After taking another look at the description for ob_start() I
began to suspect there was a difference, but the manual doesn't mention
anything about it. And the fact they use the same terminolgy for both the
settings and the functions is confusing. I can see from tests that the
htaccess/ini settings have no obvious effect on the ob functions (maybe
buffer size?).

Or other debugger recommendations besides Zend? PHP List, I won't go into a big rant about Zend, and instead simply say that while I was using Zend Studio to debug PHP pages since version 5.0. I was never really all that happy with it. It seemed to be the most complete debugging environment for PHP, so I put up with it. I will say that the Studio installation procedure has got better, but setting up a reliable debugging server has not. Now, the current version of Zend Studio (7.0) is based on Eclipse (I think since v6.0), and so I'm just not sure what I'm paying for anymore. Aptana Studio, also based on Eclipse has pretty much the exact same interface and can even connect to a Zend server. Since one of those is free, I can't see why I wouldn't switch. The issue for me is that paying for Zend hasn't really saved me much hassle, so even if Aptana has difficulties, at least they are free difficulties. The main failing point, so far as I can see, of Aptana/Xdebug, is a lack of good, clear, documentation (also note that Zend doesn't have great documentation either). Especially on how to set it up. I was wondering if anyone has used it and could provide a link or instructions on how to get the debugging environment up and running. Or, equally as valuable, would be recommendations on other debugging environments. The key is finding one that has a clear set of instructions for how to set it up (On Ubuntu/Debian Linux with a local LAMP server.) Thanks for any advice. Dave M G -- Dave, take a look at PhpED from Nusphere. I've used the Windows version very happily for the last 6 years. There is a Linux version but I haven't tried it so can't comment - from the forum I gather that most users use the Windows version. Debugging in PhpED is brilliant, but so is the rest of the IDE.

RE: [PHP] Will PHP ever "grow up" and have threading?
If you added threading to the bag of tricks it already has, you're getting into areas that make it more difficult to pick up for beginners (and that's not to mention the technical elements involved in actually adding threading to PHP) Currently the only other 'easy' language I know for beginners is ColdFusion, and that's just horrible. You wouldn't want to be responsible for sending the newbies down that path would you?! :p Thanks, Ash http://www.ashleysheridan.co.uk == That's not a good argument against implementing threading, regardless of the technical issues involved in making it work. There are plenty of more advanced areas of php that beginners stay clear of. Just because threading is available doesn't mean it will automatically be used or even considered in most projects. I wrote C code for years in a large fairly complex banking front-office system and only found a very few occasions where threading was required to get the job done. In the majority of C and C++ code you find very few examples of threading, either because it's not required (99.9% of the time) or the coder didn't feel comfortable using it and found another way to achieve the result. In the few occasions where I did use threading I would say that most the time there was no other way of achieving the required result. But the issues you need to solve with C are very different to the issues you need to solve with php. I've spent more than 8 years coding php and I haven't ever hit a brick wall because of the lack of threading, but of course every project is different and I'm sure there are situations out there where trying to work around the lack of threading can cause major hassles. But as others have pointed out you use the right tools for the job, and if php doesn't have what is required then use something else.

It means that pages are easily created as all the template/session/database handling is done by the central class. 2) Using SE friendly URL's like: http://www.somesite.com/products/22012/cool-game/ http://www.somesite.com/products/22013/other-game/ This approach seems to be becoming more common on the sites I frequent, however by accounts I've read it seems to be more intensive on apache as it requires a mod-rewrite function. 3) Using different PHP files for each page: http://www.somesite.com/viewproduct.php?product= http://www.somesite.com/viewuser.php?user=... This would appear to be the least developer friendly option? Alex. = The second option doesn't really belong here, because you could go for option 1 or option 3, and then decide whether to hide your implementation behind a mod-rewrite. Option 2 would rather be part of a separate question "what is the cost/benefit of using mod-rewrite". Cheers Arno Personally, I go with option 3 (as Arno said, option 2 isn't really an alternative option, it's something you can use with either 1 or 3) Consider a basic website with a small shopping cart and a blog. It would seem crazy to have all the logic needed for the blog and the cart being pulled in by PHP everytime you just needed to display a contact page. Far easier to keep everything a bit more modular. That way, if you need to update something, you update only a small part of the site rather than some huge core file. But, if your needs are even more simple, say it's just a very small brochure website you have, then running everything through a single index.php might not be such a bad idea. Thanks, Ash http://www.ashleysheridan.co.uk == There are many approaches to this, and I think your final design will largely be determined by what you want to do, and your own skill and experience. If you want to initialise your application, check input and load all your base api functions before calling the specific script (function) to handle the query, then maybe you can consider using a single entry point for your application. It can simplify your design and maintenance, and there are ways to ensure that access to your scripts have been initialised via the single entry point. Careful design can allow you to add new modules/scripts/whatever without having to update your single entry point each time (look at some open-source apps for examples). It also allows you to move your entire application to some place outside the document root and leave only the entry script open to the public, which can add a bit of extra security to your application. Personally I use two entry-points, one for admin and one for everything else. Then besides graphics, flash and javascript, everything else is put someplace outside the document root. The reason I settled on that approach was because the admin script can handle all the slow heavy security-checking stuff and loading additional admin api's, while the general script can be small, fast and lightweight, but won't allow any access to the admin functions. Neither script needs to be updated when adding to or changing the main application. Cheers Arno

My single entry point (or dispatch script) is only 12 lines of code and never changes, even though the application is constantly updated and expanded. It doesn't load 100's of KB, instead relies on the next (module) layer to load its own requirements. But it does ensure the environment is correct, input checked, db connected, core api's loaded. It's really six of one and half-a-dozen of the other because all designs end up at more or less the same point, but for me this was the most efficient, flexible and expandable design after trying several approaches. Even major design changes like registering modules and scripts and adding mod-rewrite can be done without needing to change the entry script. If another completely unrelated app is ever added I'll just call it's script as Ashley described. The design allows for some interesting options, like a single installed app running multiple domains.

If you want this html to get to the browser you must either echo it to the output buffer that is sent to the browser, or end your php section with "?>" so that these lines are interpreted as part of the output that is sent to the browser. If your php script is running without error then I presume you're already doing this. If that's the case then maybe it's not being put into the output buffer the way you're expecting (e.g. maybe the quotes don't match).

We're all guilty of them, but has anyone recently noticed that there is a significant number (about 35% of all traffic) that is off-topic? There have been questions on databases, JavaScript, WordPress, Apache directives, and more none of which were even related to PHP. Unfortunately, this is how dilution occurs, which often causes communities to dwindle into a defunct or otherwise low-quality state. As those of you who have been around for at least a couple of years know, we have continued to thrive here because we're not strict on the topics of discussion, and frequently [d]evolve into off-topic banter (particularly on Fridays, as it used to be). However, have you noticed the influx of extremely low-quality and/or low-class posts to the list? Couple that with the ominous silence from the formerly-frequent contributors of high-quality material, code examples, and community assistance. It is not a coincidence. This is an open list, and we don't moderate or censor any of the discussions, but before it gets out of hand, I'd like to suggest a moratorium on all off-topic posts through the end of this month --- with the exception, again, of Fridays. Which would mean that those in agreement would participate in the hiatus by not only not posting off-topic threads, but also not replying to those that are off the general topic. This isn't to say that threads can't still eventually decay into a friendly discussion, as has always been welcome, but that it shouldn't be the intent of a thread to seek assistance on topics unrelated to PHP and PHP programming in general. -- UNADVERTISED DEDICATED SERVER SPECIALS SAME-DAY SETUP Just ask me what we're offering today! daniel.br...@parasane.net || danbr...@php.net http://www.parasane.net/ || http://www.pilotpig.net/ -- It's Friday so I suppose I can respond... ;) I belong to a couple of mailing lists and always found the PHP list particularly active, focused, mature, and a tremendously helpful resource, even just following issues others raise and resolve. And Daniel, your own gentle prods to keep things on track I think sets some of the professional tone of the list. However, the subject of the list can be broad and fuzzy and can lead to some semi off-topic posts like Apache directives that affect PHP apps, JavaScript/Ajax interaction with PHP code, open-source PHP apps, etc. And even some non-PHP issues that most PHP developers will deal with at some time or another. Of course there are degrees of just how far off-topic one can go, but the fact that you can tap into a huge resource of skills and experience to find answers that can be difficult to find elsewhere is obviously very tempting. I'm sure I'm not the only one who finds some of the responses to these off-topic issues quite edifying, considering they're almost always within the broad realm of PHP-related web development (though I agree low-quality posts are useless to everyone whether on-topic or not). At the same time I can see it's a difficult balancing act to cater for everyone from total beginners to highly skilled professionals and still keep everyone on board, especially if some of the more experienced and busy users feel they're being flooded with hundreds of mostly irrelevant posts (like this one) every day. But I also think those same users have the skills and filters to quickly scan and find the posts that are useful/interesting/relevant. Personally I think this list is great, even with some of the off-topic discussion. And your own involvement has always been very professional, and of course very focused, thanks.

I'm not that familiar with date, I tend to use strftime myself (no idea why
there's both). Sounds like date's W is equivalent to strftime's %V which
does indeed return "01" for this date as there's at least 4 days of the new
year in that particular week.
Both %U and %W seem to return what you want, using strftime. I'd guess that
date would also have flags for these.

Geoff.

Whilst this is true as far as it goes, I would suggest applying deMorgan's
laws to simplify slightly to
if ( ($current_page != $saved_page) or ($current_ip != $saved_ip) or
($current_dt >= ($saved_dt + 3600) ) )
Also, the keyword versions of the Boolean operators are very low priority,
which is why you need all those extra parentheses -- if you switch to the
symbolic versions, you can leave all the internal parentheses out to give:
if ($current_page != $saved_page || $current_ip != $saved_ip ||
$current_dt >= $saved_dt + 3600)

Mike, I presume you're saying the precedence of the Boolean keyword
operators is lower than the Boolean symbol operators, but if so then
wouldn't there be less need for the parentheses? I prefer using the Boolean
keyword operators for both the readability and because of the lower
precedence. Unless I've been wrong all this while and the keyword precedence
is actually higher?

I checked the manual, the Boolean symbol operators have a higher precedence

[PHP] Apache's PHP handlers
For the past week I've been trying to get to the bottom of an exploit, but googling hasn't been much help so far, nor has my service provider. Basically a file was uploaded with the filename xxx.php.pgif which contained nasty php code, and then the file was run directly from a browser. The upload script used to upload this file checks that the upload filename doesn't have a .php extension, which in this case it doesn't, so let it through. I was under the impression apache would serve any file with an extension not listed in its handlers directly back to the browser, but instead it sent it to the php handler. Is this normal behaviour or is there a problem with my service provider's apache configuration? Trying this on my localhost returns the file contents directly to the browser as expected and doesn't run the php code. Cheers Arno

But if opened from a page hosted elsewhere with some code like require($path_to_your_image), the php code inside the image will be sent to the php handler and will be executed. Prevention is the best way to avoid hacking from image upload. Check the file extention and the file content before upload. Cheers. Steven -- Hi Steven, I agree the best way to avoid this is for the file upload script to check the file contents and that's something I'll have to sort out, currently it just checks the extension. But it's still a concern that a file with any arbitrary extension can be processed as php script as long as it has the text ".php" in the filename. I'm not worried about including the file because that would require pre-existing malicious php code, I want to prevent that malicious php code from running in the first place.

Arno: If you can request that file using a web browser, and it gets executed as PHP on your server then there is an error in the Apache configuration. Easy test: create a file in a text editor containing some PHP ( would be enough) and upload it to the www root of your site and name it test.pgif. Then hit http://www.yourdomain.com/test.pgif in your browser. If you see the PHP code or an error then you're fine. If you see PHP's info page then you need to change web host as quickly as possible. I don't care if they fix it - the fact their server was configured to do this by default is enough for me to never trust them again. -Stuart -- Thanks Stuart.

Yes, Apache offers this feature, but you don't need to configure it to work will all extensions. I'd be curious to know what their issue is with using FilesMatch, since that provides a way to disable this behaviour. And, honestly, who would have a PHP file per language? I think it's perfectly reasonable to not allow that, because duplicating PHP code across many files is an incredible stupid way to support multiple languages.

Access permissions can be set per article, per category and/or per container, for one or more users and/or user groups. If an article is assigned to 10 categories and only one of those has a permission denying access, then the article can't be accessed even if browsing through one of the other 9 categories. Currently everything works fine, with article titles showing when browsing through category or search result lists, and a message is displayed when the article is clicked if it cannot be viewed because of a permission. Now there's a requirement to not display the article title in category lists and search results if it cannot be viewed. I'm stuck with how to determine the number of results for paging at the start of the list or search. The site is quite large (20,000+ articles and growing) so reading the entire result set and sifting through it with permission rules for each request is not an option. But it might be an option if done once at the start of each search or list request, and then use that temporary modified result set for subsequent requests on the same set. I thought of saving the set to a temporary db table or file (not sure about overhead of serializing/unserializing large arrays). A sizing exercise based on the recordset returned for searches and lists shows a max of about 150MB for 20,000 articles and 380MB for 50,000 articles that needs to be saved temporarily per search or list request - in the vast majority of cases the set will be *much* smaller but it needs to cope with the worst case, and still do so a year down the line. All this extra work because I can't simply get an accurate number of results for paging, because of permissions! So my questions are: 1. Which is better (performance) for this situation: file or db? 2. How do I prepare a potentially very large data set for file or fast writing to a new table (ie I obviously don't want to write it record by record) 3. Are there any other alternatives worth looking at? TIA Cheers Arno

How are you determining (logically, not in code) when an article is allowed
to be read?
Assume an article on "user permissions in mysql" is in a container called
'databases' and in a second one called 'security' and both containers are in
a category called 'computers'
Now get a user called John who is in a group called 'db admins' and that
group gives him permissions to view all articles in the 'databases'
container and any articles in any container in the 'computers' category. Now
assume John also has explicit user permissions revoking that right to view
the article in any container.
What I'm getting at is what's the order of privilege for rights? Do group
rights for categories win out over those for containers, or do individual
user rights trump all of them overall?
I think once that's figured out, a lot can be done inside the query itself
to minimise the impact on the script getting the results.
Thanks,
Ash

The simple structure is articles in categories, categories in containers,
only one article per container/category, in one or more containers. If an
article permission explicitly allows or denies access then the permission
applies, otherwise the container/s and category/s permissions are checked.
The permission checks user access first then group. A user can belong to
multiple groups.
There's no query to handle this that can return a neat recordset for paging.
Currently the complete checks are only done for an article request. The
category list only checks access to the category and the container it
belongs to, so the list is either displayed in its entirety (including
titles of articles that can't be viewed) or not at all, and obviously the
paging works perfectly because the total number of titles is known up front
and remains constant for subsequent requests.
If I use read-ahead to make allowance for permissions and remove paging
(just keep prev/next) the problem goes away. Or I could use "best-guess"
paging, which could range from 100% accurate to 99% wrong. At first glance
that's not really acceptable, but I noticed recently Google does the same
thing with their search result
RE: [PHP] Paging and permissions
Instead of serializing the articles, you only need their IDs. Using
$sql .= ' where id in (' . implode(',', $ids) . ')';
you can load the data for a page of results in a single query. Storing the
IDs is much cheaper than the articles.
If the permissions are fairly static (i.e. access for user X to article Y
doesn't change every two minutes) you could create a calculated permission
table as a many-to-many between user and article. Here's the logic flow for
a query:
1. Run the query to find matching article IDs
2. Load permissions from table for all IDs
3. For each article without a calculated permission, calculate it and insert
a row (do a batch insert to save time)
If you flag the query in the middle tier as having been processed as above,
you can join to the calculated permissions each time you need another page.
The downside is that the code that runs the queries has to operate in two
modes: raw and joined to the permissions. If most users end up querying for
all articles, the table could grow. Plus you need to purge rows any time the
permissions for an article/user changes which could get fairly complicated.
David

Storing only the IDs is way cheaper than storing the entire resultset, and
I'd been thinking along the same lines. Getting a complete list of valid IDs
in the first place is turning out to be a different matter. The permissions
for article/user aren't that straight-forward, and in fact the most common
permissions are group/category and group/container, where an article can be
assigned to one or more category/containers. Using a temporary permission
table could be the solution. Thanks.

I started copying a 200MiB file from my desktop machine onto the Samba share.

[PHP] ip2long and ipv6
My dev and test tools are windows based and the apps deployed on linux, and
it's been working well. But moving to win7 created problems because it uses
ipv6 and code for ratings is for ipv4. Specifically, using ip2long to save
the ip as an int (to prevent duplicate votes) doesn't work in test
(win7/php5.3). I've got a quick-n-dirty workaround ("::1" converted to "0")
but it seemed a good opportunity to add code to handle ipv6 properly when
it's deployed.
I found a reference to do that in the help
(http://php.net/manual/en/function.ip2long.php), but the referenced site no
longer exists. I also found a page where Daniel Brown mentions that user
notes referencing external sites are normally removed
(http://www.lmpx.com/nav/article.php/news.php.net/php.notes/177158/read/inde
x.html) but that the note added enough value to make an exception. I'd be
very grateful if anyone could please point me to any other record of this
code, or could post it if they have a copy.
Also, I'm assuming the code returns 2 ints because of the size of ipv6, and
it's fine to change my code to store that, but I'd like to know if there's a
standard way to store ip addresses in sql for quick lookup?

[PHP] Getting knotted with quotes encoding
I've been battling with quotes encoding when outputting javascript with php. It can't be unique, so I'm hoping someone has a working solution they're willing to share. The following works perfectly as long as there aren't any single quotes in the link text: echo "$sTitle"; if $sTitle has the valueWhat's newit outputs: What's new It displays fine, but javascript complains with: Expected ')' linkmanager.php Line:525 Char:63 So I fix this by swapping the double and single quotes around: echo "$sTitle"; Now for that specific link it outputs: What's new And javascript is happy. But elsewhere there's a link Fred "Buster" Cox and it outputs: Fred "Buster" Cox Again it displays fine, but javascript complains with: Expected ')' linkmanager.php Line:743 Char:77 So it looks like I can't have links that include single quotes and double quotes, only one or the other. One work-around I thought of was to convert any link texts that included double quotes into single quotes when the content is posted, and it would then be displayed with single quotes even though the user entered double quotes. It's far from ideal but it would work, though I can think of a few situations where it would be quite confusing to the reader. Are there any other solutions that would allow both types of quotes without any conversions?

You aren't escaping the quotes correctly when they go into your output. You're
escaping them for html not javascript. Javascript (like php) escapes single
quotes inside a single quote string with a back slash.

Thanks for that Ashley.
You're right about the encoding.
I had a line prior to that:
$sTitle = htmlentities($title, ENT_QUOTES, 'ISO-8859-1', FALSE);
Which encoded the quotes.
I couldn't find anything so made a function, which might be useful for others.
It’s a first shot, I'm sure there are ways to improve performance.
I also changed the encoding to exclude single quotes.
(I'm sure the indenting will get screwed up in the mail)
$sTitle = fixSingleQuotes(htmlentities($title, ENT_COMPAT, 'ISO-8859-1',
FALSE));
.
// convert single quotes to curly quotes, xml compliant
// assumes apostrophes must be between 2 alpha chars
// and any other ' is a single quote
// ‘ = left single quote
// ’ = right single quote and apostrophe
function fixSingleQuotes($sText)
{
if (strpos($sText, "'") !== FALSE) {
// there are quotes to convert
$bOpenQuote = FALSE;
$arrAlpha = explode(' ', "a b c d e f g h i j k l m n o p q r s
t u v w x y z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z");
$arrText = str_split($sText);
while (($pos = strpos($sText, "'")) !== FALSE) {
if ($pos == 0) {
// must be an open quote in first pos
$sText = "‘".substr($sText, 1);
$bOpenQuote = TRUE;
} else {
if (in_array($arrText[$pos-1], $arrAlpha) AND
in_array($arrText[$pos+1], $arrAlpha)) {
// apostrophe
$quote = "’";
} else {
// quote
if (!$bOpenQuote) {
$quote = "‘";
$bOpenQuote = TRUE;
} else {
$quote = "’";
$bOpenQuote = FALSE;

[PHP] foreach weirdness
The following snippet is copied from the php manual:
foreach ($arr as $key => $value) {
echo "Key: $key; Value: $value\n";
}
I've always used the foreach loop that way.
But recently I started hitting some really odd problems.
See this following example that illustrates the problem:
$array = array(0, 1, 2, 3, 4, 5, 6);
foreach ($array as $index=>$value) {
if ( ($index+1) < count($array) ) {
$array[$index+1] += $value;
}
echo $value." ";
}
echo "";
foreach ($array as $index=>$value) {
echo $value." ";
}
You'd expect the output to be:
0 1 3 6 10 15 21
0 1 3 6 10 15 21
But it's actually:
0 1 2 3 4 5 6
0 1 3 5 7 9 11
If you assign the $value by reference in the first loop as someone pointed
out (and confirmed by the manual: "As of PHP 5, you can easily modify
array's elements by preceding $value with &. This will assign reference
instead of copying the value")
$array = array(0, 1, 2, 3, 4, 5, 6);
foreach ($array as $index=>&$value) {// <- assign $value by reference
if ( ($index+1) < count($array) ) {
$array[$index+1] += $value;
}
echo $value." ";
}
echo "";
foreach ($array as $index=>$value) {
echo $value." ";
}
it still does not produce the correct result:
0 1 3 6 10 15 21
0 1 3 6 10 15 15
If I watch the $array in a debugger I see odd behaviour for the last element
$array[6] when stepping through the second foreach loop.
Just before entering the second loop $array[6] == 21 which is correct.
When I move to the next line (echo $value." ";) $array[6] changes to 0 !!
As I step through the second loop $array[6] keeps on changing for each
iteration, with the following values:
0, 1, 3, 6, 10, 15, 15
And once I've left the second loop $array[6] is permanently changed from 21
to 15, even though there's no code in the second loop to change $array[6].
So what's going on here?
I confirm this by echoing $array[6] in each iteration in the second loop:
$array = array(0, 1, 2, 3, 4, 5, 6);
foreach ($array as $index=>&$value) {
if ( ($index+1) < count($array) ) {
$array[$index+1] += $value;
}
echo $value." ";
}
echo "";
foreach ($array as $index=>$value) {
echo $array[6]." ";
}
echo "";
echo $array[6];
the result is:
0 1 3 6 10 15 21
0 1 3 6 10 15 15
15
Note that $array[6] is still 15 even after completing the second foreach
loop.
If you break out of the second loop then $array[6] will be at whatever value
it was at the time you break out (ouch!)
If you assign the $value by reference in the second loop as well:
$array = array(0, 1, 2, 3, 4, 5, 6);
foreach ($array as $index=>&$value) {
if ( ($index+1) < count($array) ) {
$array[$index+1] += $value;
}
echo $value." ";
}
echo "";
foreach ($array as $index=>&$value) {// <- assign $value by reference
echo $array[6]." ";
}
echo "";
echo $array[6];
you finally get the correct result:
0 1 3 6 10 15 21
21 21 21 21 21 21 21
21
You can test this with multiple foreach loops and get the same results. If
you modify the array in the first foreach loop, then use an assign $value by
reference in the next 9 foreach loops to get the correct values (without
modifying the array), and then in the 10th foreach loop you don't use an
assign $value by reference (without modifying the array), the array becomes
corrupted.
I sort of understand the need to assign the $value by reference in the first
loop, but why is it also required in every subsequent loop where the array
is not being modified? Especially since all the examples in the manual show
it's not needed? It would appear that once you've modified an array's
elements in a foreach loop you always have to assign $value by reference in
any subsequent foreach loop using that array. And if you don't, not only
will you get the wrong results but the array itself is actually altered,
even if there's no code in the loop to alter it. Is that correct or is it a
bug? At what stage can you start using the array in the "normal" way again?
That could create hair-pulling havoc for anyone maintaining code if they
haven't noticed that somewhere previously there was code that modified the
array in a foreach loop. Maybe the answer is to always assign $value by
reference in a foreach loop regardless of what you do in that loop, but I'm
not sure what the implications are.

This looks like a bug... the last row should be the same. What version of PHP
are you using? Have you checked the online bug reports?

Hi Rob
I'm using php 5.3.5. What result do you get when you run this code?
I haven't checked any bug reports, I'll google to see where I would do that.
Your code gets round the problem, but I was specifically referring to the use
of foreach with its unexpected side-effects. There are a few different designs
like look-ahead where it seemed the obvious way to go. I know I've used this
type of foreach coding in the past, and have this nagging feeling there's a
whole bunch of code just waiting to explode. I always just assumed it worked
because it's pretty simple. I'd previously been caught out forgetting the
assign by reference in the foreach loop that modified the array but I always
caught it long before it went live, but I never considered having to also use
assign by reference in subsequent foreach loops because it so obviously wasn't
necessary. Now I'm searching through my scripts to see if there are any
potential problems caused by this (already found one), and wondering what else
I've done where I no longer have access to the sources.
BTW I'm told on another forum this issue has been discussed multiple times on
this mailing list - did I miss it? Was there a resolution?
Cheers
Arno

Hey,
the ouput you get is right. If you want your ouput you have to rewrite your
code.
Currently you are adding the value of the current index to the next indexes
value (e.g. $array[0] + $array[1]; $array[1] + $array[2]; etc.).
As I understand it you want to add the current value with the next index (e.g.
$array[0] + 1; $array[1] + 2; $array[2] + 3).
--
Hi Stephan, the first foreach loop adds the next value to the current value,
not the next index. The reason you don't get the expected result in the first
foreach loop is because you need to assign the $value by reference, as per the
php manual
foreach ($array as $index=>&$value)
But then to get the correct output from the second simple foreach loop, you
also have to assign the $value by reference, contrary to the php manual. If you
don't you get the wrong result and the array becomes corrupted. That could be
classified as a bug, or at least the manual needs to elaborate on using a
foreach when you assign the $value by reference.
Cheers
Arno

Hi, Robert
Does not seem like a bug to me ...
http://schlueters.de/blog/archives/141-References-and-foreach.html
What you should do to get the expected result:
Unset the variable after you don't need this reference any longer.
Bye
Simon
--
Hi Simon, unsetting the $value does fix the problem, but I found that any time
you assign $value by reference in a foreach loop you have to do an unset to
avoid corrupting the array unless you continue to assign $value by reference
(as illustrated in the article you linked).
So doing something as simple as:
$array = array(0, 1, 2, 3, 4, 5, 6);
foreach ($array as $key=>&$value) {
echo "Key: $key; Value: $value\n";
}
and then follow with (from the php manual):
foreach ($array as $key=>$value) {
echo "Key: $key; Value: $value\n";
}
will not only give the wrong result, it will corrupt the array for *any*
further use of that array. I still think it’s a bug according to the definition
of foreach in the php manual. Maybe php needs to do an implicit unset at the
closing brace of the foreach where was an assign $value by reference, to remove
the reference to the last element (or whatever element it was pointing to if
there was a break) so that it doesn't corrupt the array, because any assign to
$value after the foreach loop is completed will corrupt the array (confirmed by
testing). The average user (like me) wouldn't think twice about reusing $value
after ending the foreach loop, not realising that without an unset the array
will be corrupted.
BTW thanks for that reference, it was quite an eye-opener on the pitfalls of
using assign by reference, not only in the foreach loop.
Cheers

RE: [PHP] foreach weirdness
Requesting that will at least require a major-release (f.e. PHP 6.0) ... but I would rather request to add a notice or warning to the documentation of references to remind stuff like that. http://www.php.net/manual/en/language.references.php I think this is stuff more people will stumble over ... Bye Simon -- I agree it would be wrong to change php's handling of call by reference in foreach loops because there may be a need to access that reference after completing the loop. I was going to suggest there should be a warning in the manual to unset the reference after the foreach loop is completed, but I see the current online manual has that warning prominently displayed on the foreach page. I had a version of the manual from July last year that didn't have the warning, so I'll update my local manual and make sure I keep it up to date. Lesson learned (both manual and foreach references).

[PHP] Watch out for automatic type casting
I found automatic typecasting can be a bit of a gotcha.
$sText = "this.is.a.test.text";
if ( $pos = strpos($sText, "test") !== FALSE) {
echo substr($sText, 0, $pos)."<".substr($sText, $pos,
strlen("test")).">".substr($sText, $pos+strlen("test"));
}
The code seems logical enough, and the expected result would be:
this.is.a..text
In fact it ends up being:
tis.a.test.text
The reason is $pos is typecast as TRUE, not int 10, presumably because it's
in the same scope as the boolean test.
Then when $pos is later used as an int it's converted from TRUE to 1.
You have to bracket the $pos setting to move it into its own scope to
prevent it being typecast:
if ( ($pos = strpos($sText, "test")) !== FALSE) {
No doubt it's mentioned somewhere in the php manual, I just never came
across it.
Just thought I'd highlight one of the gotchas of auto typecasting for any
other simpletons like me.
Cheers
Arno

It could be expanded to if ($a = foo() != TRUE) But that wouldn't get the expected result due to order of precedence, though at first glance you could reasonably expect it to work because of if (!$a = foo()) being valid.

[PHP] Generating foldout menus in php
This may not be directly php related but I'm hoping that generating the code with PHP will keep it on topic. I'm looking for a way to generate dropdown/foldout menus (horizontal and vertical) on the fly, but all the javascript solutions I've seen use absolute or relative pixel positioning, which means I can't use them because I don't know at the time of generating a specific menu item how many pixels across or down the preceding items have already used. I'm currently using a javascript menu that works really well, but all the top-level menu items have to be preset with specific x-y pixel coordinates, and all the subsequent items are then relative to the top-level items. So I can generate the second-level and subsequent items on the fly but not the top-level items. Is there a way to use css or dhtml or something else (maybe something in javascript that I missed) to do this?

I can envision a way to use php with a couple of other languages to provide drop-down and pop-out menus, but that would be more complicated than just using css with js, like so: http://sperling.com/examples/menuh/ http://sperling.com/examples/menuv/ Why complicate your life? Cheers, tedd -- Hi tedd Thanks, that's pretty much what I was looking for. I found something similar at cssplay, except the examples I saw didn't use .htc file. Like your examples the cssplay code only runs on IE5.5 and up (and other browsers). Not sure yet if that would be a problem. I don't have IE5 to test with, so I don't know if there's a graceful fallback that would still allow the user to navigate. As you said, it doesn't look like there's a solution to fit all browsers and versions.

I found ZS slow and cumbersome, and not very intuitive (probably due to unfamiliarity more than anything else). I'm sure each has it's strengths and weaknesses. I decided on PhpED because (a) it was fast and intuitive and I felt comfortable with it straight away, coming from c dev background using IBM dev tools, (b) it had everything I expected in an IDE and more, (c) the response from NuSphere and the forums was quick, (d) it was much cheaper than ZS. Since making the choice I find PhpED very stable, and the updates are frequent with real useful new features and functionality. The latest version has a feature I requested a few months ago so the developers are generally good at listening to feedback and requests. And the debugger is excellent. PhpED is the single most important dev tool I have and well worth the investment, and I'm not sure the extra cost for ZS would have given me any extra value. But I'm sure there are many ZS users who would disagree. Best advice is do what I did - download both trial versions and give them a thorough test yourself.

A well-maintained list of free and commercial PHP IDE's on the php.net site would be a great idea, especially if it also had links to reviews, and also included the mix-n-match IDE's I see some people on the list use. And/or maybe a forum on php.net dedicated to PHP IDE's, with user polls. Then whenever the IDE thread pops up the response would be to look at the web site (RTFWS). The only downside might be the resources to run it. BTW jammer, if you start using php for big projects I'd recommend NuSphere PhpED, but it's overkill if you just want to dabble. There's a trial version if you want to check it out, and a good tip is they drop the price every now and then for promotions (wish I knew that 4 years ago).

[PHP] PHP date: ISO year = loss of hair
I'm battling with getting the last week number using date(W, $unixdate). If the date is 30 December 2007 ($unixdate=1198965600) then date(W, $unixdate) returns 01. I know that according to the ISO spec, the last week of the ISO year has 28 December in it, so in this particular case the last week number of the ISO year is 52. However 30 December is in the following week, week 53. How do I get the correct value of 53 for 30 December 2007? I'm thinking along the lines of: if the date is greater than 28 December then use the week number of 28 December; then check every day between 28 December and the date to see if a Sunday occurs and if so add one to the week number. It looks like it will work but seems ridiculously laboured for such a simple issue. Am I overlooking something obvious here - is there something I've missed about PHP date?

[PHP] Conditional popup driven from server-side
I know popup windows are a client-side issue, but I can't figure how to create and close a popup window from the server side only on condition, otherwise display normal browser page. What I want is to accept a form, check the input, if there are errors return them to the browser, if there aren't errors then popup a modal window and start processing (a possibly long process) while displaying results in the popup window, then automatically close the popup after processing is complete and redirect to normal browser page with the final results. I want to use the popup to (a) feedback ongoing progress to the user, and (b) keep the browser side alive because the process could take several minutes. Googling for +php +popup is getting me nowhere, all the results are for javascript. I know how to create a link or button that when clicked will create a popup that will display the results of a php script, but I need to do it the other way round.

If you want to provide feedback on the form, then look into Ajax or use output buffering and flushing to push out a status message as the form is processed. You could do this in a javascripted pop-up window or on the window they submitted the form. If it takes your script minutes to process a form you need to look into your processes. I'd suggest verifying the form had all the pieces and then advising them you will email them when the registration or what-not is complete. HTH, Wolf === I fully understand this is a client side issue, but figured there may be a way for the server to drive it using smoke and mirrors. For instance if the input is ok I thought of redisplaying the completed form with an onload to popup a modal window, then output progress to the window until the process was finished, then send something to the window to close itself. But after that I get stuck because I don't know how to make the underlying browser page request the final results from the server, or have some way for the php script to push the results to the page without a request. Or maybe it's all javascript, with the browser page waiting for the window to close before requesting the results? (though I see some timing issues with that solution, unless I create a temp results page waiting for the browser's request). Has anyone on the list done anything like this, or have any pointers, examples or ideas?

[PHP] Problem with script timing out in php 4.4.8
I recently picked up an issue when I upgraded my IDE, where the browser
window timed out while I was debugging the code. I checked with support and
was told the problem was with php 4.4.8 which they'd upgraded to, so to
confirm I installed 4.4.8 and ran a test - and it seems there is a problem
with 4.4.8.
The test was:
change max_execution_time from 30 to 600 in php.ini - phpinfo confirms
max_execution_time=600
Test timeout - sleep for $t seconds";
echo "sleeping ".date('h:i:s')."";
sleep($t);
echo "stop sleeping ".date('h:i:s');
?>
$t=59 works fine, but $t=70 times out.
(Windows 2000, Apache Release 10324100)
I ran the same test successfully with $t=500 seconds on a different machine
running php 4.3.4, everything else the same as the original test pc.
What bothers me a bit is 4.4.8 has been available since February and
checking the archives I see no-one else has reported this problem, which
seems highly unlikely, so I'm wondering if this is specific only to my
environment somehow. Has anyone else had problems with max_execution_time in
4.4.8?
Cheers

RE: [PHP] Problem with script timing out in php 4.4.8
The fact that 59 seconds worked suggested the ini settings was in effect,
otherwise it would have timed out after 30 seconds (default ini setting).
But I also tested your suggestion:
Test timeout - sleep for $t seconds";
echo "max execution time set to ".ini_get("max_execution_time")."";
echo "sleeping ".date('h:i:s')."";
sleep($t);
echo "stop sleeping ".date('h:i:s'); ?>
?>
Same result, $t=59 works but $t=70 times out
Cheers
Arno

Could you try setting the max_execution_time with ini_set and confirming the
status of it with ini_get ?

RE: [PHP] Forum coded in PHP with mail and news gateway
Not sure about the gateways but you can look at www.phpbb.com -Original Message- From: Michelle Konzack [mailto:[EMAIL PROTECTED] Sent: 11 June 2008 04:52 To: PHP - General Subject: [PHP] Forum coded in PHP with mail and news gateway Hello, because it is actual for me while having some problems with Ubuntu's LAUNCHPAD (does not support threating) I like to know, whether there is a light Forum software written in PHP availlable. It should support: 1) PostgreSQL (my own database) 2) MySQL (my current hosting provider offer it only) 3) Threating 4) Gateway to mailinglist including threating 5) Gateway to usenet including threating 6) Subscriber only 7) Scanning for SPAM :-D I like to install it on my "devel" website and have the need for a category for each software package I have. So it is not a big thing with currently 61 packages bu maybe increase to arround 150. My current mailinglist software is "courier-mlm" which works nicely. Any suggestions?
