Hi,
I am trying to understand odd(different) behavior of the header function
under two different environments.
Here is the code which I am trying to execute from two different servers
<?
header ("Set-Cookie: c1=value1;path=/; domain=.domain.com");
header ("Set-Cookie: c2=value2;path=/; domain=.domain.com");
?>
When executed from server1(OS X), both cookies are set in browser, but when
executed from server2(Linux), only the second cookie is set.
server1 and server2 are running different OS and php version as below. I
know I could add $replace=false option on the Linux server, but I am trying
to understand the different behavior of header() function on these two
servers. Any thoughts?
server1 - OS X
----------------------------------------------
PHP Version 5.2.4
System Darwin host2.domain.com 8.8.4 Darwin Kernel Version 8.8.4: Sun Oct
29 15:26:54 PST 2006; root:xnu-792.16.4.obj~1/RELEASE_I386 i386
----------------------------------------------
server2 - Linux
----------------------------------------------
PHP Version 5.3.5
System Linux host1.domain.com 2.6.18-164.15.1.0.1.el5 #1 SMP Wed Mar 17

I don't have a clear idea about this because I always use setcookie(),
but something tells me that this has something to do with output
buffering and friends.

Well, according to the manual, you need to be using the FALSE parameter anyway
since "By default it will replace, but if you pass in FALSE as the second
argument you can force multiple headers". So the wrong behaviour is on the
(older) OS X server, but I'm as confused as you as to why this should be as
there is no indication in the manual or the ChangeLog that the default
behaviour has changed at any point.
Cheers!

Hi guys,
the code files are being cached. and modifications in methods are skipped
and not executed. is there any parameter that i can pass it from ini file?
this has been so annoying for me. restarting apache, windows, etc does not
even help. im running apache 2.2.19, php ts 5.3.6 on windows 2003 r2
any ideas how to avoid this situation? thanks

It seems you have a wrongly configured opcode cache runnning about which
you're not aware of.

basically using default configuration, have not changed anything except the
path for extensions in php.ini.
and there is nothing installed/configured to cache anything.

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.

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.

Well thanks, cos I only started doing this whole webby programmy developy
technobabble thing yesterday and I'm still learning the basics!*
How do you know that "modifications in methods are skipped and not
executed"? By looking at the output shown in your browser? The output that
could be cached by proxies and/or your browser?
Or are you running them on the command line, in which case some sort of
opcode cache is probably the culprit, or you're not running the code you
think you are.

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.
