#35096 [Opn]: still trouble with mod_rewrite/apache2

ID: 35096 Updated by: sniper@php.net Reported By: rob at burningsoda dot com Status: Open Bug Type: Apache2 related Operating System: * PHP Version: 5CVS, 4CVS (2005-11-04) (snap) New Comment: Make that SCRIPT_NAME. Previous Comments: ------------------------------------------------------------------------ [2005-11-07 15:37:05] sniper@php.net FYI: SCRIPT_FILENAME != PHP_SELF ------------------------------------------------------------------------ [2005-11-07 13:52:06] rob at burningsoda dot com As a further note, $_SERVER['PHP_SELF'] contains "/phpbug/index.php/" if URL-rewriting took place while $_SERVER['SCRIPT_NAME'] correctly returns "/phpbug/index.php". This happens even with output buffering disabled and leads to the conclusion, that the original bug is not in the buffering code. Beware! This fact (PHP_SELF != SCRIPT_NAME or PHP_SELF nonexistant) can lead to extremely subtle bugs. ------------------------------------------------------------------------ [2005-11-07 12:35:21] rob at burningsoda dot com After rebuilding Apache2 and PHP5-dev on different machines the whole weekend about 2 million times and wondering why some showed the bug, some not, I eventually tracked it down to the following simple configuration setting (*drum roll*): *** output_buffering *** To trigger the bug, set "output_buffering = On" or (e.g.) "output_buffering = 4096", TO BYPASS THE BUG (listen up, bug plagued Joomla!/Wordpress/etc. users) SET "output_buffering = Off" in your php.ini. This bypass works for PHP 4 & 5. Cheers, rob. PS: If I extend my testcase to <?php ob_start(); echo($_GET['myarg']); ob_end_flush(); ?> with "output_buffering = Off" that still does _not_ trigger the bug. Maybe that helps. ------------------------------------------------------------------------ [2005-11-06 22:41:36] free4cd at yahoo dot de 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 ------------------------------------------------------------------------ [2005-11-06 19:47:49] remko at elvandar dot org 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 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
