RE: [PHP] mod_rewrite q's: syntax?

Well, I added this to the end of my .htaccess:

Seems to work well, but I am still concerned about

[PHP] imap_search and multiple criteria

[James Nunnerley]

Does the imap_search support multiple criteria?

 

I've got the following successfully returning the correct results:

 



 

However, when you try and put them in the same search 

e.g. $search = "BODY \"test\" OR SUBJECT \"test\""

 

It fails...

 

The only way in which I can see this can be done is by joining the various
arrays that are returned.  Is this best?

 

Thanks

So use the built in tokenizer functions which know exactly what's
enclosed text and what is php code. Much quicker and more reliable
than trying to do the same job with regular expressions.

[PHP] String /pattern formatting extraction question

[Andy]

Hi to all, 

I have the following pattern for a string:

text1 /ptext2 /otext3

Now, I want to extract the text by "patterns" from this string by the following 
rule:

no pattern -> text1 (what is before /o or /p)
/p -> text2 (what is after /p)
/o -> text3 (what is after /o)

The order betweeen /o and /p can be switched, so there is no rule that /p is 
before /o.

How can I do this? I tried ereg but no success.

Andy.

I had to eliminate that option because his IP is varying drastically. There

[PHP] RSS Generation

[Robbert van Andel]

I am working on creating some RSS feeds on my website using PHP.  I'm still
learning RSS but it seems easy enough. I managed to create the RSS giving
the file a PHP extension.  When I tried saving it with an xml extension and
adding a .htaccess file to the directory in which the file was saved, I get
prompted to save the file instead of being able to view the file in a
browser.  The only line in the .htaccess file is AddType
application/x-httpd-php xml.  

 

First off, and I'm sorry that this isn't a PHP specific question, but does
RSS require an XML extension?  And if it does, how do I get the server to
serve the PHP file correctly if I rename it with the xml extension?

 

Thanks,

Robbert van Andel

No, you can use any extension you like for the RSS document, including
.php its the contents that matters.

text1 /ptext2 /otext3

text1(whitespace)/ptext2(whitespace)/otext3


The ideea is to extract the texts before and between /o and /p.
$html = "asdäüü ö ö vf /pxtestxx/ostestss";
eregi("^([^/.*]*)", $html, $reg); print_r($reg); //text is in reg[1]
eregi("^(.*)/p([^/.*]*)", $html, $reg); print_r($reg); //text is in reg[2]
eregi("^(.*)/o([^/.*]*)", $html, $reg); print_r($reg); //text is in reg[2]


This example works, but I thought there might be a better way to extract the
texts, with a single ereg or preg_match.

Well... slightly.

preg_match( '#^(+)/p(.+)/o(.+)$#',
preg_replace('#^(.+)(/o.+)(/p.+)$#', '$1$3$2', $html), $reg);

I had similar problems when trying to roll-my-own RSS feed with php.
Michael is right that it doesn't matter what your file extension is
(you probably don't even need that htaccess directive) as long as the
file is served as XML. Try adding a header at the top of the file:

header("Content-type: text/xml; charset=utf-8");




...

I also use the Firefox browser which has a built-in XML browser that
allows me to do a quick validation of the XML. You can also use
www.feedvalidator.org to troubleshoot your feed once its online.

*lol*. personally I prefer the other format which was what I tried to
illustrate with my original example:



All it means, is that once you have the name of a function in a variable
you can invoke the variable as a function and it will invoke the
function matching the variable's value. Some of this stuff can be really
useful for doing backwards compatibility with older versions of PHP:

[PHP] how to assign a value to a variable inside a class

Hi there,

I would like to assign a value inside a class like this:

var $db_username = $old_name;

Unfortunatelly this does not work and I do get following error:
Parse error: syntax error, unexpected T_VARIABLE, expecting T_OLD_FUNCTION or 
T_FUNCTION or T_VAR or '}'


Thank you for any hint on how to place a correct syntax on this.

use a setter function. Direct var assignments must be simple constants. A

[PHP] A question about max_execution_time

[Eric Butera]

Dear List,

I have been working with a PHP script that curls a file from another
server.  This works fine on my local machine, but not on our live server.
The script takes about 400 seconds to execute completely.  I was under the
impression that my call to set_time_limit(900); was helping.  Well, I took
that line out and nothing changed locally or on the server.  In fact I even
tried this little test:

max execution time: '. ini_get('max_execution_time');
sleep(40);
echo "done!";
echo "Script Executed Time: ". Util::displayMicroTime(
$_SCRIPT_START_TIME, Util::getMicroTime() );
die(''.__FILE__.__LINE__);
?>


Outputs:
max execution time: 30
done!

Script Executed Time: 40.01
/Users/eric/Sites/test/member_get_update.php26


Now why did this work?  Shouldn't the script have timed out after 30
seconds?

Thanks in advance!

Eric

The information in set_time_limit() might help:

http://us3.php.net/set_time_limit

"Note:  The set_time_limit() function and the configuration directive 
max_execution_time only affect the execution time of the script itself. Any 
time spent on activity that happens outside the execution of the script such 
as system calls using system(), stream operations, database queries, etc. is 
not included when determining the maximum time that the script has been 
running."

Actually, the dot is the end of a sentence ... damn my excellnet grammar skills

In the htaccess file, I hadn't included a dot at either end of XML. I think I'm

Ray,

Thank you for your response.  I did read that in the manual, I promise.
That is why I included the sleep function in my example.  Shouldn't the
sleep function count as execution time?  One thing I didn't metion earlier,
for the sake of simplicity, is that my script is pulling an XML file.  After
I get the XML file I parse through it which also takes time too.  The
recordset is about 6 thousand records so it does take a while.

Right after I sent that I started wondering if sleep() would be counted in the 
time or not.  I would think it would, but it *could* in the background just 
run the system sleep, which might not be counted...  I don't know that much 
about the sleep function to tell you.  Parsing the XML should cause it to 
time out if it was longer than 9 seconds though... interesting situation...

At the moment I don't have much else for you :(

[PHP] simpleXML - simplexml_load_file() timeout?

[darren kirby]

Hello all,

My website uses simpleXML to print the headlines from a few different RSS 
feeds. The problem is that sometimes the remote feed is unavailable if there 
are problems with the remote site, and the result is that I must wait for 30 
seconds or so until the HTTP timeout occurs, delaying the rendering of my 
site.

So far, I have moved the code that grabs the RSS feeds to the bottom of my 
page, so that the main page content is rendered first, but this is only a 
partial solution.

Is there a way to give the simplexml_load_file() a 5 second timeout before 
giving up and moving on? 

Here is my function:

function getFeed($remote) {
if (!$xml = simplexml_load_file($remote)) {
print "Feed unavailable";
return;
}
print "\n";
foreach ($xml->channel->item as $item) {
$cleaned = str_replace("&", "&", $item->link); 
print "$item->title\n";
}
print "\n";
}

PHP 5.1.2 on Linux.
thanks,
-d

'sleep' doesn't count.

That's even in the 3rd to last User Contributed Note. :-)

Always read the Notes.  You may have to wade through some [bleep] but
you'll find some nuggets of info well worth the effort.

The primary goal of set_time_limit is to keep scripts from slamming
the server and taking ALL the CPU time.

If the script is sleeping, it's not taking CPU time.

I missed the beginning of the thread, but if you need to count 'sleep'
time, you'll just have to code it yourself somehow...

I suppose the first item on your agenda might be to contribute a
get_time_spent() function to the PHP source that returned whatever
value PHP is using to track this CPU usage. :-)

[PHP] Browser-based scanning

[Dan Harrington]

Hello everyone,

I am needing to build a system that allows a user to visit a website driven
by a unix hosted apache web server running PHP, login, and scan an image off
of a TWAIN-compliant scanning device, and upload it to the web server where
PHP and ImageMagick do some post-processing of the image.

Does anyone know of a PHP-based solution that does something like this?  The
link from the scanning device to the web server is the big unknown for me.
Do I have to use ActiveX?  Can ActiveX interface with PHP?

Thanks
Dan

First off, check that httpd.conf is even USING .htaccess
You can find/read httpd.conf, or you can make a new directory with
index.html in it, surf to it, then put something totally bogus in an
.htaccess file in that directory.
If .htaccess is "on" then you'll get a 500 server error because of
your bogus .htaccess settings.

Next, you need to check WHAT you are allowed to override in .htaccess
For that, you'll have to actually read httpd.conf, if you can, or do a
LOT of experiments if your webhost has it non-readable.  (My webhost
used to do that, but he got smarter)

If all else fails, you can do:

http://example.com/rss.php/whatever.xml

where rss.php is your REAL script, and whatever.xml is junk that
Apache and PHP will cheerfully ignore.

Actually, they don't TOTALLY ignore it, they store it in
$_SERVER['PATH_INFO'] for you, in case you need it.

I'd be awful careful here...

SOME versions of Microsoft IE are particularly stoopid about dealing
with URLs and Content-type etc.

SOME versions are even more weird when you add GET parameters to non
HTML document URLs. E.G.
http://example.com/myphpscript.pdf?date=5/1/2006
Where myphpscript.pdf has been ForceType in .htaccess to be PHP.

If I was you, I'd still try for the .xml ending and don't give the web
browsers who might link to your RSS feed any opportunity to [bleep]
up.

Hey guys... implementing a permission system and just wanted some advice.

If i have permission A

How do the permissions relate to each other, for eg if I select

to true, but then if I set B to false or C to false, or both does that 
affect permission A?


Assuming that B, and C dont have implied rights you should be able to 
turn both of them off while leaving A on, but then that breaks the rule 
for A having implied permissions B and C.


Any help appreciated.

I dont know the Grammar for specifying logic anymore, but

IF A implies B + C, then reverse logic should imply that if !( B && C) 
== !A. In other words, it shouldnt matter which of B or C is false.


Or you could specify if ((!B) || (!C)) then A==FALSE.

But more importantly, YOU are specifying the permission system, so you 
must define the priority, implications, etc..


I would personally prefer a rule which had A = ( B && C ). In other 
words, A does not imply B and C are true, but is defined by there being 
true, or is dependent. The possible confusion wil come when you specify 
permissions as 'implications' rather than as combinations of 'conditions'.


My 2 cents.

Will there always be at least one /p or /o?...

And I'm assuming you don't need the whitespace.

And that text2 and text3 must not have embedded whitespace.

Then you can do something like:



You may want to get a program called "The Regex Coach" which lets you
type patterns/input and see the output in real-time.  Incredibly
handy/useful.

Also, your syntax looks AMAZINGLY like the GetOpt patterns of command

of pre-built libraries to handle your strings.

YMMV

Another alternative, if mod_rewrite confuses you as much as it does me...

.htaccess

  ForceType application/x-httpd-php

DocumentIndex folder

folder


On the plus side, this doesn't force people into example.com when they
went to www.example.com -- It just works. :-)

PS

I you do stick with mod_rewrite, turn mod_rewrite_debug *ON* and tail
-f your http error_log for awhile.

You'll learn a lot about what will/won't work for mod_rewrite in your
rules...

The warnings about mod_rewrite debugging/logging performance issues
are a bit over-stated, I think...

Or, at least, you need to do this on a development server with "real"
traffic patterns for your testing, if doing it live is a non-option.

Doing it on only the URLs *you* think of typing doesn't count.  Those
pesky real users can come up with some really interesting URLs to
type... :-)

Why do you do this on every request? Why not have a cron job retrieve an
update every 20 minutes or whatnot and stuff it into a database table
for your page to access? Then if the cron fails to retrieve the feed it
can just leave the table as is, and your visitors can happily view
slightly outdated feeds? Additionally this will be so much faster that
your users might even hang around on your site :)

Cheers,
Rob.

[PHP] String is not zero-terminated

In order to attempt to figure out why my script segfaults PHP (5.0.4,

That then gives me warnings such as:

This is a very interesting idea, but I am not sure if it is suitable for me at 
this point. First of all, one feed in particular can change in a matter of 
seconds, and I do want it to be as up to date as possible. Secondly, this is 
just for my personal site which is very low traffic, and it is not 
inconceivable that getting the feed every 20 minutes by cron would be _more_ 
taxing on the network than simply grabbing it per request...

And to be fair, when everything is working as it should the feeds are 
retrieved in a matter of seconds, and I don't think it is annoying my users 
at all. It is the 0.5% of requests when the remote site is overloaded (or 
just plain down) that I want to provision for here.

I do like this idea of caching the feed though. I think in my situation 
though, rather than prefetching the feed at regular intervals it may be 
better to cache the most recent request, and check the age of the cache when 
the next request comes. This way, I would not be needlessly updating it for 
those times when the page with my feeds goes for a few hours without a 
request.

Of course, this still wouldn't solve my original problem.

Well personal websites break all the rules. There's nobody to answer to
but yourself :)

Looks like simplexml neglected to offer a timeout option. You would
probably be better off using curl to retrieve the content, then using
simplexml_load_string(). Curl does allow you to assign a timeout.

Rob.

Re: [PHP] simpleXML - simplexml_load_file() timeout?

Maybe you can read the contents of the feeds using fsockopen() and
stream_set_timeout() to adjust the timeout, or stream_set_blocking()
to read it asynchronously, and then load the xml with
simplexml_load_string().

PS: I forgot to reply to all and mention you'll have to send the GET
http command and headers, check the php manual for examples.

Hello, and thanks for the response,

As Robert Cummings suggested above, the easy solution is to use curl, which 
does offer a timeout option, and then feed it to simplexml_load_string().

I am writing some code now...

Thanks, and have a good one,

Yes.

I should have said from the get-go I was running as CLI, which, unless
I'm really being naive, means mod_perl cannot be involved.

Is the TWAIN device tied to the server?

Cuz PHP runs on the server.

So if the scanner is connected to their desktop, PHP isn't going to be
involved, at all, really.

Your question might be:  "Does anybody know of any web-based
widget/control that can be used to force a user's scanner to operate?"

But then, it has nothing to do with PHP.

The ONLY way you could tie in PHP would be if you were to use PHP-GTK
http://gtk.php.net and if PHP-GTK had some kind of interface/module to
talk to scanners, which I sincerely doubt, but it's at least in the
realm of "possible" instead of "impossible" which is where you are at
right now trying to tie PHP on your web-server to my scanner.

I don't think it's a particularly good idea that you'd be able to mess
with MY scanner from your web-site, thank you very much!

Who knows what sort of private document I might have in my scanner!

Think about this for awhile, and I think you'll realize why your
question not only doesn't make sense, it SHOULDN'T make sense.

Unless you're building a desktop application with PHP GTK.

I assume you have zend_debug turned on.  Basically php will be safe
with this warning, since it shouldn't be relying on the \0
terminator but the actual length of the string.  I belive this
warning is in place to help migrate from the dependency of \0.

One thing you might want to check is what is triggering this error,
if you are doing a strlen() call this error shouldn't be issued,
IMO.  If operation you are doing rely's on the terminating \0, it
most likely should get fixed in php.

One thing you could check is the archives of the php-devel list to
see if there is talk about this.

HTH,

You can just use fopen() to avoid all that.

eg.

$fd = fopen($url);
stream_set_blocking($fd,true);
stream_set_timeout($fd, 5);  // 5-second timeout
$data = stream_get_contents($fd);
$status = stream_get_meta_data($fd);
if($status['timed_out']) echo "Time out";
else {
  $xml = simplexml_load_string($data);
}

As for your caching, make sure you create the cache file atomically.  So 
how about this:


function request_cache($url, $dest_file, $ctimeout=60, $rtimeout=5) {
  if(!file_exists($dest_file) || filemtime($dest_file) < 
(time()-$ctimeout)) {

$stream = fopen($url,'r');
stream_set_blocking($stream,true);
stream_set_timeout($stream, $rtimeout);
$tmpf = tempnam('/tmp','YWS');
file_put_contents($tmpf, $stream);
fclose($stream);
rename($tmpf, $dest_file);
  }
}

That takes the url to your feed, a destination file to cache to, a cache 
timeout (as in, fetch from the feed if the cache is older than 60 
seconds) and finally the request timeout.


Note the file_put_contents of the stream straight to disk, so you don't 
ever suck the file into memory.  You can then use a SAX parser like 
xmlreader on it and your memory usage will be minimal.  You will need 
PHP 5.1.x for this to work.


You could also use apc_store/fetch and skip the disk copy altogether.

Perhaps, then, you should:
maintain a list of URLs and acceptable "age" of feed.
Attempt to snag the new content upon visit, if the content is "old"
Show the "old" content if the feed takes longer than X seconds.

You'll STILL need a timeout, which, unfortunately, means you are stuck
rolling your own solution with http://php.net/fsockopen because all
the "simple" solutions pretty much suck in terms of network timeout.
:-(

It would be REALLY NIFTY if fopen and friends which understand all
those protocols of HTTP FTP HTTPS and so on, allowed one to set a
timeout for URLs, but they don't and nobody with the skills to change
that (not me) seems even mildly interested. :-( :-( :-(

want, or maybe even exactly what you want, I might as well just

No, he can't.

Sorry, Rasmus. :-)

If the URL is not working at the time of fopen() then you'll sit there
spinning your wheels waiting for fopen() itself to timeout, before you
ever GET a valid file handle to which one can apply stream_set_timeout
and/or stream_set_blocking.

That can take MUCH too long.

So you're STUCK with fsockopen, which DOES take a timeout parameter
for OPENING the socket, as well as giving one a stream to which
stream_set_blocking and stream_set_timeout can be applied.

But then you are stuck re-inventing the damn wheel with any protocol
you'd like to support like GET/POST, HTTPS (ugh!), FTP and so on.

All of which is buried in the guts of the Truly Nifty fopen,
file_get_contents, and so forth, but is utterly useless if you care at
all about timing out in a reasonably-responsive application.

So you have do all the junk to send things like:
GET / HTTP/1.0
Host: example.com
yourself, and God help you if you want to support HTTPS.

Actually, curl MAY be the better solution -- but my boss doesn't have
curl installed, so I was screwed anyway...

This is why I (and others) have put in a Feature Request to get
fopen() and friends to have some kind of programmatically changable
timeout setting.  Said Feature Requests invariably get marked "Bogus"
and then commented with something like the non-solution above. :-)

Oh well.

It *can* be done; You just have to type WAY too much junk to do
something very simple and very commonly needed.

I really do like this idea, as I would rather use an old feed than just print

Thanks for that, it looks like interesting code, if not a little over my head. 
I am just a duffer here. I will certainly play with it some more. As for 
curl, I realized I didn't add curl support myself, so I am rebuilding PHP 
now... 

When I do get something figured out I will post results here. Problem is, with 
either method I need to find a feed that is slow to test with. If I test it 
with a bunk url it will just 404 immediately right? Is there a way to

Using the example given at the link above:



We have one function that works one way.



However, doing it this way, the function can serve two purposes. I

Plus, in the first function, I can't send it a reference (i.e., a

I dunno about similating a slow connection, but you can write a very
slow server... :-)

my_slow_rss_feed.php
Darren Kirby';
  sleep(10);
  for ($i = 0; $i < strlen($data); $i++){
echo $data[$i];
flush();
sleep(1);
  }
?>

Of course, that doesn't simulate the slow connection part of it...

If you have 2 machines, you can unplug the network cable, start your
script, then plug the cable in after 5 seconds.

That's gonna make it pretty slow to connect, almost for sure. :-)

If anybody is goofy enough to complain about the performance of
strlen() in the for(...) statement, you're clearly not paying
attention. :-) :-) :-)

I'd guess it's to simplify things.

Having been involved in a big cms that used references all over the 
place (everything was OO), it was extremely hard to find / track down 
where they should be and where they were missing - which caused memory 
blow-outs where they were not used, and segfault crashes where they were 
incorrectly used.


If they were all in the function definitions, I don't have to worry 
about that particular problem.


However, it's something the developers would have to give a definitive 
answer on.

Have you considered running php -s from the command line, which syntax
highlights your source file for you, the searching for whatever color
codes in your php.ini are used for functions?

For that matter, you could custom-code the choices for the color and
make the functions read in a separate php.ini

I believe you're thinking more of the C++ style of returning by reference.  
This article should help explain how references work, and how to return 
references... most specifically check the "Returning References" section.

Re: [PHP] simpleXML - simplexml_load_file() timeout?

[Martin Alterisio \"El Hombre Gris\"]

Maybe it's too late to say this, but if your real problem is that you 
don't want the function reading
the rss feed to block the rest of your page, you can always put the 
output of the reading of the feed

on a separate page, and include this through an iframe.

darren kirby wrote:


Hello all,

My website uses simpleXML to print the headlines from a few different RSS 
feeds. The problem is that sometimes the remote feed is unavailable if there 
are problems with the remote site, and the result is that I must wait for 30 
seconds or so until the HTTP timeout occurs, delaying the rendering of my 
site.


So far, I have moved the code that grabs the RSS feeds to the bottom of my 
page, so that the main page content is rendered first, but this is only a 
partial solution.


Is there a way to give the simplexml_load_file() a 5 second timeout before 
giving up and moving on? 


Here is my function:

function getFeed($remote) {
   if (!$xml = simplexml_load_file($remote)) {
   print "Feed unavailable";
   return;
   }
   print "\n";
   foreach ($xml->channel->item as $item) {
   $cleaned = str_replace("&", "&", $item->link); 
   print "$item->title\n";

   }
   print "\n";
}

PHP 5.1.2 on Linux.
thanks,

You can just use fopen() to avoid all that.


No, he can't.

Sorry, Rasmus. :-)

If the URL is not working at the time of fopen() then you'll sit there
spinning your wheels waiting for fopen() itself to timeout, before you
ever GET a valid file handle to which one can apply stream_set_timeout
and/or stream_set_blocking.


I thought it was the case of an overloaded slow-responding server, not 
one that is down.  For the initial connection just set your 
default_socket_timeout appropriately if you are not happy with the default.


So you just add 1 line to my example:

function request_cache($url, $dest_file, $ctimeout=60, $rtimeout=5) {
  if(!file_exists($dest_file) || filemtime($dest_file) < 
(time()-$ctimeout)) {

ini_set('default_socket_timeout',$rtimeout);
$stream = fopen($url,'r');
stream_set_blocking($stream,true);
stream_set_timeout($stream, $rtimeout);
$tmpf = tempnam('/tmp','YWS');
file_put_contents($tmpf, $stream);
fclose($stream);
rename($tmpf, $dest_file);
  }
}

Problem solved.

Yes, try this forms class that comes with plug-in named AJAX form
submit. It can submit any form using without reloading the whole page.
On the server side you can make the class respond to an AJAX form
submission with several types of actions like updating parts of the page
to give the user some feedback. Take a look at the test_ajax_form.php
example script.

That is not exactly AJAX, but rather DHTML (HTML page elements generated
dynamically with Javascript.

It can be something as simple as:

I've added a Note to 'fopen' so maybe others won't completely miss

This is a very interesting idea, but I am not sure if it is suitable
for me at
this point. First of all, one feed in particular can change in a

seconds, and I do want it to be as up to date as possible. Secondly,
this is
just for my personal site which is very low traffic, and it is not
inconceivable that getting the feed every 20 minutes by cron would be
_more_
taxing on the network than simply grabbing it per request...


Perhaps, then, you should:
maintain a list of URLs and acceptable "age" of feed.
Attempt to snag the new content upon visit, if the content is "old"
Show the "old" content if the feed takes longer than X seconds.

You'll STILL need a timeout, which, unfortunately, means you are stuck
rolling your own solution with http://php.net/fsockopen because all
the "simple" solutions pretty much suck in terms of network timeout.

If it's anything like the helpful note I added about using copy( source,
dest ) where dest accidentally points to source (due to linking), you'll
get a nice retarded email like the following:

---

You are receiving this email because your note posted
to the online PHP manual has been removed by one of the editors.

Read the following paragraphs carefully, because they contain
pointers to resources better suited for requesting support or
reporting bugs, none of which are to be included in manual notes
because there are mechanisms and groups in place to deal with
those issues.

The user contributed notes are not an appropriate place to
ask questions, report bugs or suggest new features; please
use the resources listed on 
for those purposes. This was clearly stated in the page
you used to submit your note, please carefully re-read
those instructions before submitting future contributions.

Bug submissions and feature requests should be entered at
. For documentation errors use the
bug system, and classify the bug as "Documentation problem".
Support and ways to find answers to your questions can be found
at .

Your note has been removed from the online manual.

- Copy of your note below -

User tip... it can be completely befuddling if you don't realize your
source and destination files are the same (this can happen with
directory links). When this happens there are a couple of
possibilities... at first I was using php 4.4.0 and the files just
became 0 length. The second, outcome after I upgraded to 4.4.2 (since I
didn't realize the problem) was that the copy function returned a
failure. This was tricky to track since there's no error output
indicating why the copy failed :)

Ummm, that was a sincere "I'll keep it in mind". And I know all about
typing away with a newborn sleeping on my chest, a 1 year old pawing the
screen, a 2 year old mashing the keys and cackling mischievously.

I'm very appreciative, but at the same time, I don't feel like I
shouldn't comment on the potential of getting your note trashed like so
much spam. Don't forget, adding a note IS contributing. I usually add as
I see fit, I've added in the past, I'm sure I'll add in the future. But
now I'm a little on the twice shy side of the coin.

Exactly, it doesn't happen by itself, neither do the notes. It's a
dovetailing arrangement. People add notes, people trim spam. It takes
both for either system to work. Agreed, though that adding notes isn't
the same as spending countless hours pruning.

Cheers,
Rob.

I'll keep that in mind for the future when I have more free time (2 kids
under 3 is good for keeping me occupied beyond work atm :).

Point taken, just sort of feels like  slap in the face after you go to
the effort to write a useful note :)

Cheers,

I've added a Note to 'fopen' so maybe others won't completely miss

If it's anything like the helpful note I added about using copy( source,

Yes, but just keep in mind that the folks on the other end make the 
effort every single day to cull through hundreds of these.  We have 
small kids and real jobs as well.  I am typing this with a 4-year old 
sitting in my lap doing his best to make a dinosaur stomp on my keys. 
So while I sympathize with the fact that the work you put into this note 
wasn't appreciated, please recognize that you are not being very 
appreciative of the hundreds of hours of work the folks on the other end 
are putting in.  In general the user notes in the manual are useful. 
There isn't much spam, and when something slips through it gets caught 
rather quickly.  This stuff doesn't happen by itself.

[PHP] flash file to recognize SESSION or REQUEST variables?

[Sunnrunner]

A client asked me this question. Does anyone know what it means or can
someone explain and give me an answer. 

Thanks. T

How can we get the link in the URL of the flash file to recognize SESSION or
REQUEST variables? You know like GET or POST? I need to do something like.

url =
"https://secure.store.com/HousewivesUnleashed.306/buy.cfm?p=1000141&m=306&dc
wid=$_REQUEST['aid']&udfo2=$_REQUEST['sid']";

as opposed to what we currently have.

url = "https://secure.
store.com/HousewivesUnleashed.306/buy.cfm?p=1000141&m=306";

Thoughts?

[PHP] Need MySql Help Please

[marvin hunkin]

Hi.
any mysql gurus out there using a tool called EasyPHP 1-8?
i am using a my sql tutorial, and says needs the command line interface, so 
can run my sql commands from the dos prompt.

have got the PHP MYSQL ADMIM to load into the easy php 1-8, gui interface.
and when i type http://localhost/mysql/ it loads the browser, but would like 
the command line interface for version 5.0 of the my sql databaser admin 
server.
now if any good soul, who uses my sql, or my sql admin, or easy php, can 
show me how to set up the command line interface for Easy Php 1-8, then let 
me know.
have tried looking on the net, and looking in the documentation, and 
folders, but cannot seem to set it up.

okay if any one can help me out, let me know.
cheers Marvin.
ps: need this info, as doing the tutorial towards the database assignment 
for my course.

RE: [PHP] flash file to recognize SESSION or REQUEST variables?

[Dan Harrington]

You are either asking one of two things, and I am not sure which:

A) How to send information using GET or POST out from flash to a script file
SendAndLoad is the flash function
http://livedocs.macromedia.com/flash/mx2004/main_7_2/wwhelp/wwhimpl/common/h
tml/wwhelp.htm?context=Flash_MX_2004&file=1419.html


B) How to get Flash to load variables passed to it via HTTP GET?
Flash automatically loads these variables into the _root timeline
So
http://foo.bar.com/someflashfile.swf?variable1=joy
You would have _root.variable1 and the value in that variable would be "joy"

Hope this helpsand sorry if I misunderstood your question.
Dan

Re: [PHP] Need MySql Help Please

[Joe Wollard]

Marvin,

As much as we try to keep this list PHP-only I think it's hard to
ignore the ties between PHP and MySQL. Most of us learned both
technologies simultaneously. Still, you may want to put [OT] on your
future email subjects to indicate that the question is 'off topic'.

On the matter of MySQL's command line: From what I can see on
http://dev.mysql.com/downloads/mysql/5.0.html it looks like when you
download the Windows binaries you don't get the option of just
downloading the client or just downloading the server - you are
downloading both (someone correct me if I'm wrong) in the 'essentials'
package. I'd imagine that when you run the installer it gives you an
option to install the server / client packages. As long as you told
the installer to give you the server and client both then you should
be in good shape. All you should need to do is make sure that A) the
MySQL binary (probably C:\Program Files\MySQL\MySQL Server
5.0\bin\mysql) is in your PATH environment variable and that B) the
server is running (which from the sounds of things, it is). If it's in
your path you should be able to start the client shell by simply
typing "mysql -u marvin -p" or similar.

You also might check out MySQL's documentation on running MySQL from
the command line in Windows
http://dev.mysql.com/doc/refman/5.0/en/windows-start-command-line.html

Good luck!
- Joe

Oz,

>From your command line, try:

pecl install domxml

You'll need to be root to do so, but as long as you have PECL/PEAR
installed this should give you domxml. Remember to restart your web
server after doing so.

Re: [PHP] I am not able to download domxml for PHP5

[Joe Wollard]

Of course you said you're running PHP5so that won't work.
According to the site it would be best for you to use the DOM that
comes pre compiled with PHP. http://us3.php.net/manual/en/ref.dom.php

Sorry about the mix up on my part.
