Description:
------------
I cannot disable output_buffering on Windows Server 2008. I have tried the following in the main php.ini:
* output_buffering = Off
* output_buffering = 0
* ;output_buffering = Off

No matter what I do, output_bufferings stays stuck at 4096.

I installed using the installer. I verified with the latest version of Sysinternals Process Monitor that the php.ini I am editing, c:\program files (x86)\php\php.ini is indeed the only php.ini file that is being opened by *any* process when I execute a php file.

While I believe that they are separate issues, http://bugs.php.net/bug.php?id=45501 is somewhat related.

Expected result:
----------------
Output buffering should indicate as disabled or off for at least one of the variants that I put in php.ini per above.

Actual result:
--------------
Here's the top part of phpinfo:

What exactly does phpinfo() say for this ini option?
 [2008-07-23 13:46 UTC] aren at cambre dot biz 
phpinfo indicates output_buffering is 4096 regardless of how I have it set in php.ini.
 [2008-07-23 14:06 UTC] jani@php.net 
Using this script: <?php phpinfo(); ?>

What _exactly_ is on the full row in phpinfo() about output_buffering?
If you do not set output_buffering at all in your php.ini it won't be enabled. (default value is 0 for it!)

It says "output_buffering	4096	4096" regardless of how I have output_buffering set in php.ini.

I tried all of the following:
;output_buffering = Off
output_buffering = Off
output_buffering = On
output_buffering = 1234

This is the php.ini inside C:\Program Files (x86)\PHP.

I have run Process Monitor to confirm that this is the only file named php.ini that is being accessed during PHP execution.

I even reset IIS (iisreset.exe) (yes, while running cmd.exe in administrative mode), and that had no effect. I had left output_buffering = 1234, but phpinfo still shows 4096.

1. Get http://snaps.php.net/win32/php5.2-win32-latest.zip
2. Get rid of ALL (and I mean ALL) existing PHP dlls/exes from your machine. (AFTER stopping your webserver and anything else which might use them)
3. Install the fresh snapshot.
4. Make sure there are NO php*.ini files in your system.
5. Start your webserver.
6. Check phpinfo(). No php.ini file should have been loaded at this stage. And output_buffering should have 0 0 for the values. And PHP version is 5.2.7-dev..

Before I do this, is http://snaps.php.net/win32/php5.2-win32-latest.zip
 a stable release? Or is this experimental?
 [2008-08-09 00:01 UTC] jani@php.net 
It's the development version (== not released) of upcoming PHP 5.2.7.
Anyway, if you can't reproduce this problem on some other machine, it's clearly some isolated problem in your server, in other words: bogus.
