FYI: SCRIPT_FILENAME != PHP_SELF

As a further note, $_SERVER['PHP_SELF'] contains "/phpbug/index.php/"
if URL-rewriting took place while $_SERVER['SCRIPT_NAME'] correctly
returns "/phpbug/index.php". This happens even with output buffering
disabled and leads to the conclusion, that the original bug is not in
the buffering code.
Beware! This fact (PHP_SELF != SCRIPT_NAME or PHP_SELF nonexistant) can
lead to extremely subtle bugs.

After rebuilding Apache2 and PHP5-dev on different machines the whole
weekend about 2 million times and wondering why some showed the bug,
some not, I eventually tracked it down to the following simple
configuration setting (*drum roll*):
*** output_buffering ***
To trigger the bug, set "output_buffering = On" or (e.g.)
"output_buffering = 4096", TO BYPASS THE BUG (listen up, bug plagued
Joomla!/Wordpress/etc. users) SET "output_buffering = Off" in your
php.ini. This bypass works for PHP 4 & 5.
Cheers,
rob.
PS: If I extend my testcase to
<?php ob_start(); echo($_GET['myarg']); ob_end_flush(); ?>
with "output_buffering = Off" that still does _not_ trigger the bug.
Maybe that helps.

Same Problem with PHP 4.4.1 and 5.1 snapshots.
If rewrite is enabled you get a blank page. No error in log file or
else.
Problem with Joomla and vBulletin/vBSEO if rewrite engine is turned on.
If rewrite is disabled all works fine.
My .htaccess for Joomla:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) index.php

I had similiar problems with apache2+mod_rewrite and php
4.4.1. All sites that made use of mod_rewrite broke and gave
a white page (nothing in the error log though), all other
sites that use php but not mod_rewrite were working
perfectly.
my .htaccess:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) index.php
