Fatih, please explain what you mean by "the code files are being

Those browsers should be fine, but forcing a reload (the control/shift +
refresh) is always worth trying.
Maybe I should compile php myself disabling things i dont need and see it

You can see what's in your PHP build by creating a script that just contains
the following..
Run that and check the output. If you got the binary from php.net then
chances are that you don't have any opcode caching modules in there.
It's also worth doing a variation on Micky's suggestion - when I want to
make sure a script has actually been executed rather than cached data being
served I put a call to echo date('r'); in an appropriate place. That way the
script output will display the current date and time which should change
with each request.

Re: [PHP] caching problem
OP: Can we see the methods in question? Have you tried running the code on a different server/host? Have you added any scaffolding to your methods in order to test your caching theory? This would be the first thing I would try (i.e. create random number (or whatever), concat with variable vals generated via method, other.)

RE: [PHP] caching problem
Fatih, I am sorry spell check auto corrected your name, I was not changing your name on purpose. It was not my intension to piss you off. I understand your frustration, trust me. I am running 5.3.6 on Windows Server 2008 R2 IIS, I am running massive class based methods in my own framework. I am trying to help you narrow down the issue. I never blame PHP first because in my trouble shooting steps, I never get to PHP before I find the issue. Segmentation Faults: that prevent the php script from completing locking up resources and causing a nightmare chain of events. It dumps the process at the fail point can look like it is a PHP thing but it is not. This can explain sometimes it works and sometimes it does not. This can be caused by a host of reasons: Buffer Overflow, Attempting to access memory the program does not own.

RE: [PHP] caching problem
Faith, I actually did read from the beginning of the message. That does not make sense. PHP files are cached intentionally, the system does not Cache PHP on its own. Sounds to me like you have an issue re-declaring an object or calling the right script/path/class/method something. I have never heard of PHP being cached unless it was intentionally cached it. Thank god for security reason! HTML output?? Sure all the time helps the browser load the content faster. I have a real issue with who ever told you that PHP is being cached, because if that was the case there is SERIOUS security hole in your PHP. I am doubting that. I have cached PHP, it can be done. Are you using APC(Alternative PHP Cache)??? I would not suggest it with complex scripting using classes and methods they are the whole reason NOT to cache. That’s just my opinion. Richard L.

RE: [PHP] caching problem
If the issue is a caching proxy or browser caching I suggest you look into
controlling the page caching header.
You can expire the header.
// calc an offset of 24 hours
$offset = 3600 * 24;
// calc the string in GMT not localtime and add the offset
$expire = "Expires: " . gmdate("D, d M Y H:i:s", time() + $offset) . " GMT";
//output the HTTP header
Header($expire);
Just a thought.

Since restarting Apache does not help, the problem is obviously outside the web
server. There are two possibilities I can think of...
* Browser caching
* Proxy caching
See if clearing your browser cache helps. If not then you probably have a proxy
between you and the server that's caching the content.

Oops. There was an extra period at the end there (after PHP_SELF).

Re: [PHP] Caching Problem
Use header("Location: page.php"); to redirect the browser, you should
allways do it after a post that changes or adds or deletes some data on
the server.

Re: [PHP] Caching Problem
Hi, Roland,
There might be a better way to do this, but you could try to use the
header() function after your upload takes place to redirect the browser to
the same page, using GET. Something like...
http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].");
}
?>
Or something like that. HTH,
Jed

[PHP] Caching Problem
Hi I have a problem with caching on IE 5.1.4 on Mac Os X. (PHP 4.0.5) The page I want to use is a simple file upload page that works by: Rest of document. The form action returns to the same page (to allow you to upload another file). This works fine, but if you press the refresh btn, the file keeps uploading pictures. If you click in the address bar & press return, this does not happen. I have included the http headers to prevent caching as described in the documentation, but this hasn't seemed to work. Is this a quirk of the browser/os combination or is there something i'm missing. TIA Roland -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Caching problem...?
Hello, I'm having a problem with my Apache/PHP setup. I create a PHP page and test it in a browser, and the page loads and everything is fine. However, when I make a change to my PHP script and reload the page to see my changes, the same output from PHP is given to me. I have to save the page as a new file and load the new file to see any changes. I've turned off caching in my browser (Mozilla) and I've even closed the browser and reloaded it, and I get the same page. The only thing that works is restarting Apache. I'm running Debian with the Debian packages for Apache (1.3.23) and PHP (4.1.2). I've tried looking at the configuration and I know there has to be an easy answer, but I can't find it. I've read the documentation for both, and I've searched the web for answers, but I just don't know what's going on here. Any help someone could provide would be greatly appreciated. Thank-you.

[PHP] Caching Problem
Hey all,
I'm trying not to cache a page. I have the following code:
$return = split(" ", exec("vmstat"));
$cpu_top = 100;
$return = $cpu_top - $return[count($return) -1];
which returns the amount of idle cpu time. The problem is this, every
time the page is loaded, it always show the first value when the page
was first loaded. I tried adding :
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
all randomly, and together, but nothing seems to work. I can run one of
my binaries in a forever loop causing the cpu not ever to be idle, but
still nothing. Help?
Thanks in advance,
Paul
