Re: [PHP] [PHP-GEN] Check Boxes
Try something along these lines:
...
Date:
Time:
Cost:
Colour:
...
...
mysql_query("SELECT " . implode(',', $_REQUEST['columns']) . " FROM
tablename");
...
?>
This should product a query like
SELECT date,time,colour FROM tablename;
And it's a lot neater than writing a huge chunk of code to generate your
column list when a little judicious use of built in functions can do it
all for you.

Re: [PHP] Array inside Class
From the manual:
In PHP 4, only constant initializers for var variables are allowed. To
initialize variables with non-constant values, you need an
initialization function which is called automatically when an object
is being constructed from the class. Such a function is called a
constructor (see below).

Re: [PHP] mysql_connect does not connect
Sam Your problem probably does stem from the extension not being installed. You say you're using (IIRC) mySQL 4.1 This requires you to use the mysqli extension, not the mysql extension As you're on windows, it's probably just a case of uncommenting the extension=php_mysqli.dll line in your php.ini, but I'm not sure as I don't have much experience configuring PHP for windows. Anyway - as far as I can tell from what you've said, that's likely to be your problem - your timeout is occurring because the mysql extension cannot connect, not because of any firewall issues. From the manual entry on MySQL (http://www.php.net/mysql): This MySQL extension doesn't support full functionality of MySQL versions greater than 4.1.0. For that, use MySQLi. If you then look at the entry for MySQLi (http://www.php.net/mysqli), you'll see this: The mysqli extension allows you to access the functionality provided by MySQL 4.1 and above. Then this page (http://www.php.net/manual/en/install.windows.extensions.php) about installing extension on windows should get you the rest of the way.

Re: [PHP] Removing strange chars from array (or string)
Zoran Sounds like your problem is with line endings - your unix (i presume) box ends its lines with a newline (\n) Windows ends lines with a carraige return followed by a newline (\r\n or CRLF) Notepad doesn't recognise a newline on its own as either a valid character or a valid line ending, so it displays it as a box Wordpad is slightly cleverer from the sound of things, and correctly interprets your newline characters trim() probably won't help because it only trims whitespace from the ends of the string - it won't strip it from the middle if you're building up your output line by line, try trim()ming it line by line otherwise you might want to look into regexes to strip repeated newlines Cheers chris Zoran Lorkovic wrote: Hi Well, when parsing html page data I want to save is saved in txt file.

Re: [PHP] fopen problem, 5 line script
Irrelevant, Warren Mag, the point is that you're trying to use a function (filesize) that uses the stat() system call. This function is not supported using the http wrapper to fopen (because HTTP doesn't support it at all) So regardless of whether you should be using the file name or the handle (it's the name, btw), the call will fail because you're trying to stat() a file which isn't supported. Thus filesize() is failing (with a warning), and fread() is then failing because filesize() returns false, which evaluates to 0. Hope this has made things clearer, if not, a quick check of the manual entries for stat, filesize and Appendix L (http://uk.php.net/manual/en/wrappers.php) may help Cheers chris Vail, Warren wrote: I thought filesize required the file name, and not the fileptr???

Re: [PHP] mysql_connect does not connect
All this is irrelevant; while you're still trying to use MySQL 5 with mysql_connect() instead of mysqli_connect(), it WILL NEVER WORK Sort that out first before you start worrying about firewalls - you can't test the firewall if you can't ever have a successful test case. Cheers Chris Markus Mayer wrote: On Thursday 16 September 2004 05:06, Sam Hobbs wrote: It is my understanding that the firewall is not supposed to be relevant. I It is our experience at my employer that the firewall in XP-SP2, as well as other firewalls that are available, are very relevant. have not seen anything saying it is supposed to be. We also have not seen any documentation about "problems" with such things after installing SP2, but we have problems. Things that worked before don't work any more, especially client side things. Our three small Windoze servers have given our Windoze administrator more than enough work recently. If it is true that it is not supposed to be relevant, then simply saying it is just causes confusion. If you had said that the firewall is not supposed to be relevant, but try disabling it anyway, then I would say that I am totally able to think like that too. It is reasonable to try things like that to diagnose a bug. flame blocked by firewall. If you can find something in the MySQL documentation saying that the firewall needs to be disabled eventhough the server and client are the same system, then that would sure help. I am not asking you to; I am saying that that is what would help. SP2 is so new that its effects are still being evaluated by a lot of people. At the moment, I think the best place to get information about its effects is forums like this one. Formal documentation will be updated in time as more experience is gained. The info I got from our Windows admin is that with SP2, the MS SQL server on one machine was apparenty unaffected, but the MySQL on another was. Dropping the MS Firewall in SP2 allowed connections again. Client side, SP2 has caused nothing but problems for us to the point where we as administrators are now saying to our users "it was working before you installed SP2, and after you installed SP2 it stopped working, so it's your problem". IE is especially problematic, and when someone calls up and says they have a problem with IE and have installed SP2, our response is that we no longer support IE and tell the users to install Mozilla, and if they still have problems when they try Mozilla, they can call us back. We haven't heard from any of them again, and our help desk girls have always been able to quickly sort out the problems users have when they first try Mozilla. I looked back in this thread and saw that you used Zone Alarm as a firewall. You need to allow MySQL connections to localhost, and that regardless of which firewall you use. If you filter such connections out, PHP scripts will not be able to connect to your MySQL server. This is because PHP makes a TCP connection to the MySQL server, also when it is running on the same machine as you PHP/Apache (at least this is my understanding). You can of course continue refuse all external (that is not from localhost) connections to whatever service is running on your machine. I think something to this effect has already been said in this thread, but at the moment I don't want to search for the post. While the flame war in this thread has been amusing to read, it's amusement value for me has more or less run out. My impression is that you still don't have the thing working, and the only solution left is to configure your firewall to allow connections to your MySQL server from localhost. If you would do this, and it works, please post to the list to reflect this.

Re: [PHP] Infinate looping
Are you by any chance doing something like this?
while (1)
{
$dbh = mysql_connect(x, x, x);
mysql_query(...);
sleep(10);
}
If so, you could run into that maxclients problem very quickly because
you're not closing those mysql connections (they'll time out eventually,
and there are persistent connection options in php.ini), but as you're
only running one thread, you should never really have more than one
connection open at a time - a well-placed mysql_close() may do wonders
Of course, that's just a guess as to how your script might be executing
If it really matters to you, you can get a cron job to execute (I think)
every second, which would probably be a better solution
Or http://uk.php.net/manual/en/features.persistent-connections.php might
have some useful info - I don't know because I haven't taken the time to
read it :)

Basically I have a file that connects to a database, before the loop, and
then checks the database for new messages. If there are, it displays them
accordingly
if via php through the
web server i suspect you're running into a "maxclients" problem (your
client connections aren't closing fast enough so you're using up all
the client connections).
I was thinking this could be the case. Is there any way not to use up
maxclients? I'm just running one loop, though it may be infinite.
if you're running this through your web server, a much more efficient
approach would be via a php-cli or perl application. either of these
should be able to run as continuous tasks without causing other
problems.
I would run through command line but I'm not sure how. This is a chat script
anyway, and I'm not sure if I have command line abilities on my production
server.
Also, I was thinking of maybe using a socket server. Are socket servers
allowed by mainstream web hosts or do you need certain privileges to open a
socket and connect to them?

Like Jason says, the definitive list is from *your* php_info(), not the hosting companies - you might like to send them copies of both and ask them to explain the differences. Cheers Chris missshus wrote: When I log into my hosting account I have access to the official phpinfo() script and it shows certain extensions (like mbstring for example) as available, but they are not available to my scripts. Every time I try to use them I get "Call to undefined function" errors. At first I just avoided those extensions but now I really need the mbstring extension so I started looking for solutions to this problem. I realized that my phpinfo() script gives a different output than the official one, and I think it's because it's showing a different path to php.ini. My script shows /usr/local/lib as its php.ini path and the official one shows /etc/php4/apache. So, after reading some of the older messages on this list I tried putting "SetEnv PHPRC /etc/php4/apache" in my .htaccess file. Then, my script was showing that as its php.ini path but it was obvious it was still giving the same output. I also remember (from the archives) someone else said his phpinfo() was showing the same path, but he said there was no php.ini file at /usr/local/lib on his system. And all I remember from his thread is that php is probably just using the default settings and showing /usr/local/lib as its path. I don't know if there is a php.ini on their system at that path or not, all I want to do is use the extension the hosting company is showing as available in it's phpinfo() script. I've tried contacting them, but they have given me some really stupid answers (free hosting, that's kind of what I expected). I think it's also important to point out that this it the first time I've opened a hosting account so I'm not really sure if this is their problem or mine. Shouldn't both phpinfo() scripts give the same results? Any help would be really appreciated. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Pear::Image_Text - how to change background color from black
Guys
Without hacking the pear library, does anyone know of any way (using the
API) to change the background color of an image created with Image_Text
from black?
The bg is black because the image resource is created using
imagecreatetruecolor() which returns a black image - this is on some of
lines 550-569 in the pear source. I could change this, but I'm sure
Tobias must have written in some way for this to be changed - the docs
are of course minimal, and I can't find anything in the source.
The text is nice and yellow, as specified in the code below, the only
problem is changing the background from the lovely black default.
Can anyone help me out? Code follows:
Cheers

[PHP] [SOLVED] [PHP] Pear::Image_Text - how to change background color from black
Just FYI
I figured it out - there is an $options['canvas'] option which accepts,
amongst other things, a handle to an image resource. Trivial then to use
imagecreate() and imagecolorallocate() to create a white-background
starting point.
Sorry for wasting everyone's time

Re: [PHP] interesting behavior of ob_end_flush() in __destruct()
it seems that php first ends output buffering and then calls then destructs the objects. so the output buffering is still ended when the destructor is calles. one has to unset the object to reverse that order manually. aRZed If I remember correctly, there were a number of posts about this subject on the internals list before PHP5 came out. I seem to recall that the gist of it was that destructors are called *after* the script terminates. Someone mentioned that output from destructors (echo, print, etc) may not be passed to the browser at all due to the connection having (possibly) been closed. I haven't searched through the archives to refresh my memory, but it's something to bear in mind. I wonder whether error messages are also not passed to the browser...

Re: [PHP] Query Returning Error
You can get around this problem more easily by putting your variables
inside curly brackets when they appear inside strings.
See here:
http://uk.php.net/manual/en/language.types.string.php#language.types.string.parsing.complex
Or as an example:
$Query01 = "SELECT * FROM Users
WHERE UserID = '{$_POST['TXT_UserID']}'
AND UserPassword = '{$_POST['TXT_UserPassword']}'";
$Result01 = mysql_query($Query01) or die ("Error 01: " . mysql_error());
?>
Note also that you didn't quote the index you were using inside the
$_POST array. This is wrong - it will work in "raw" PHP because it will
be interpreted as an undefined constant, and thus replaced with the
string, however the behaviour inside a quoted string is even less
correct, and will almost certainly not do what you expect.
Hope this helps
Cheers
Chris

Re: [PHP] Advanced maths help (part 2)
I think you've a couple of problems with your second problem (problem
problem problem).
First of all, you're setting $dst_h to 0, which gives you a height of 0
- IIRC that's not what you wanted :)
You should be setting that $dst_h = 120 as you always want it to be 120px
I reckon that your code should look more like this:
// assuming that we're creating two thumbnails, one has h=120, w=?, the
second has h=120, w=90
// we'll also assume that the original has h=600, w=800
$src_img = imagecreatefromjpeg("tgp1.jpg");
$src_h = imagesy($src_img); // 600
$src_w = imagesx($src_img); // 800
$dst_h = 120;
$dst_w = $src_w * ($dst_h / $src_h);
$dst_img = imagecreatetruecolor($dst_w,$dst_h);
imagecopyresampled ($dst_img, $srcImage, 0, 0, 0, 0, $dst_w, $dst_h, $src_w, $src_h);
// so far so good, now, lets save the file
imagejpeg($dst_img, 'test.jpg');
unset($dst_img);
// time for problem 2
// first we need a h=120, w=90 image
// image size for h=120, w=90 thumbnail
$dst_h = 120;
$dst_w = 90;
$dst_img = imagecreatetruecolor($dst_w, $dst_h);
// we will be copying to the top left corner of the new thumbnail
$dst_x = 0;
$dst_y = 0;
// now, let's find the top-left offset from the larger original image
$src_x = ($src_h - $dst_h) / 2;
$src_y = ($src_w - $dst_w) / 2;
// no need for imagecopyresampled as we'll be doing 1-1 pixel copying here
imagecopy ($dst_img, $src_img, $dst_x, $dst_y, $src_x, $src_y, $src_w,
$src_h);
// so far so good, now, lets save the file
imagejpeg($dst_img, 'test2.jpg');
unset($dst_img);
?>
Hope this helps (although I haven't tested it)

ImageJPEG($dst_img,'test.jpg');
echo "The bitch works!";
** code end problem 2 **

do I have to do everything from the start for problem

Re: [PHP] Sessions not destroyed
As Marek has stated a number of times, the session options in php.ini are meant to be set to reasonable values for the usage pattern for your server, in order that you can achieve a balance between a /tmp or /var/tmp of several zillion kilobytes, and a constant 100% cpu usage as the gc routine runs again and again. That's all it is. If you wish to time out your sessions for security purposes, you need to handle that security in your application. Security is the responsibility of the developer, and should always remain that way. Anything else is leaving you open to trouble. To restate, the session.gc_maxlifetime defines how long the session must have been inactive in order for it to be SAFE to be gc'ed. That's why it's session.*GC*_maxlifetime and not session.security_maxlifetime. The setting has no bearing on when a session MUST be gc'ed. That is up to the developer to deal with - hell, with session.gc_divisor = 0, you can have session files which are never deleted if you desire - that doesn't mean your users should never be logged out, now does it? Hope this clears things up a little. Cheers Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

if (empty($_COOKIE['bookmarks']) || !($bookmarks =
unserialize($_COOKIE['bookmarks'])))
{
$bookmarks = array();
}
Does the same with only one call to a potentially weighty function.
Cheers

Re: [PHP] Callback functions inside classes - how to?
From the manual:
http://uk.php.net/manual/en/language.pseudo-types.php#language.types.callback
If you want to change things in the callback, the function (or method)
should accept its parameters by reference.
e.g.
class A
{
function name(&$a, $b, $c)
{
$a = $b . $c;
return;
}
function parse()
{
// whatever
// then (calls $this->name())
$parser->set_handler( "root/page/title", array($this, 'name') );
// or (calls A::name())
$parser->set_handler( "root/page/title", array('A', 'name') );
// more whatever
}
}
Hope this helps
Cheers

Hi again,
I have always been wondering how this is done properly:
Here is an example:
[snip]
class A {
function name( $a, $b, $c) {
$tmp = array();
$tmp[a] = $a;
.
array_push( $GLOBALS['XMLStack'], $tmp );
}
function parse() {
.. some definitions .
$parser->set_handler( "root/page/title", "name" );
. some more stuff here .
}
}
[/snip]
What I want is to have the callback function name as it is in the above
example. But, obviously, the above code won't work. So, how do I tell the
set_handler function that it must use the name function from the class?
Using:
"A::name" or "$this->name" (if instantiated) . how do these callback
function calls work, because the same issue is with the xml handler
functions in php4 (have not as yet been to v5).
Also, how can I get the data from the callback function out without using
$GLOBALS? I cannot just return an array, can I?
Any ideas.
Thanks so long.
Thomas

Re: [PHP] Nested foreach ?
Stuart,
Having read what you've written so far, you may want to try something
like this.
In your HTML (I've left the selects empty, but you can see what I mean):
...
Then in PHP
foreach ($_POST['skills'] as $skill)
{
$skillname = $skill['name'];
$yearsused = $skill['years'];
$lastused = $skill['used'];
...
}
?>
Hope this helps
Cheers

Re: [PHP] 'Intelligently' truncate string?
You could also try a combination of html_entity_decode to change all entities back, then truncate it, then use html_entities to get back to the encoded string. Hope this helps Cherrs Chris Robert Cummings wrote: On Mon, 2004-10-18 at 14:35, Murray @ PlanetThoughtful wrote: Hi All, I'm working on a page where I'm attempting to display article titles in a relatively narrow area. To save from ugly wrap-arounds in the links, I've decided to truncate the article title string at 20 chars. This works well except where the truncate occasionally falls in the middle of a HTML entity reference (eg or © etc). after you do your usual truncation just add the following: $truncated = ereg_replace( '&[[:alpha:]]*$', '', $truncated ); You may need to replace alpha with alnum since I can't remember if there are any entities with digits :) Cheers, Rob. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Session
Deleo We had an interesting conversation on this last just last week regarding the length of sessions. The title of the thread is "[PHP]Sessions not destroyed". Try searching the archives with that text. I believe Marek's and my own messages may have the information you're looking for - basically, PHP doesn't provide a mechanism to *guarantee* expiry of sessions - only to deal with garbage-collecting defunkt ones. Any explicit session-expiry will have to be implemented by the end-user; i.e. you. Hope this helps Cheers Chris Deleo Paulo Ribeiro Junior wrote: Hello! I am trying to make my pages last for only 1 minute but I am not been successfull. I have already changed session.cache_expire = 1 in php.ini (USING RedHat) but nothing happens.

Re: [PHP] File Copy
Aidal
Could you post the relevant parts of your code so we have a little
context to work in?
You say you're copying a file from one location to another on the same
server. If this is the case you are very unlikely to be in need of the
ftp family of functions, which are only valid for use over an
established ftp connection.
I suspect that the file is indeed now owned by the webserver
has it changed from aidal:somegroup to nobody:nogroup or something like
that?
Post us some code and the answers you get will probably be more useful
Cheers

Hi NG.
I'm experiencing some problems when trying to copy a file from one

dir1/subdir1/some_image_name.jpg -->

When I do this the file permissions changes and I'm no longer the owner
of
the file. I tried to use chmod('the_new_file', 0777); but it doesn't
work,
because chmod() wont let me change the permissions since I'm not the

of this new file.
The owner should now be the user the Web server is running as.
To change file ownerships you need to use the PHP FTP functions.

Re: [PHP] Strange Array Error
Shaun The problem is that you've assigned $test_array[] = array(); This means that the first element ($test_array[0]) is an array. You're then trying to add $i to it, as in $test_array[$i] = $test_array[$i] + 1; in terms of types what you're doing is array = array + integer Which doesn't make any sense. If you change the first line to $test_array = array(); Then the individual elements will all be NULL, which evaluates to 0 in an integer context, and you will get the result you expect.

Re: [PHP] Form executes differently in IE than in FireFox?
Murray I'm guessing that IE sends $recid = '' whereas firefox doesn't send it at all because it's an empty form field. Try checking for empty($recid) instead - that way you can check that it not only exists (as in isset) but also that it has a value (i.e. not '', NULL, 0 or FALSE) Hope this helps Cheers crhis Murray @ PlanetThoughtful wrote: Hi Jason, I wasn't under the impression that posting 18ish lines of code would be thought of as inconsiderate, but thank you for the pointer all the same.
