ID: 13932 Updated by: jeroen Reported By: bonseb@free.fr Old Status: Duplicate Status: Bogus Bug Type: Output Control Operating System: Windows NT4 SP6 PHP Version: 4.0.6 New Comment: Submitted twice -> Bogus Previous Comments: ------------------------------------------------------------------------ [2001-11-05 09:55:01] bonseb@free.fr Pressed submit twice by error :( Valid bug is #13933 ------------------------------------------------------------------------ [2001-11-05 09:10:54] bonseb@free.fr [Might be related to bug #11213] Using : NT4 SP6 Apache 1.3.20 PHP 4.0.6 Zend Optimizer 1.1 (bug reproduced without also) I have a quite short PHP page needing to log something, and then switch to another PHP page. I use the following PHP code : error_log ($message, 0); header("Location: new-location.php"); I then get the following error message : Cannot add header information - headers already sent If I remove the call to error_log, the problem disappears, but I won't get the event logged :( Thus, error_log must be 'the one' producing the unexpected output. If I swap the two calls, (header first, then error_log), I'll get to new-location.php, but nothing will get logged :( If I specify a filename in the call to error_log, and leave it in second position (see following example), it works fine (except I don't automatically get the date and IP address of client like I used to get in Apache's log). error_log ($message, 3, 'd:/program files/apache group/apache/logs/error.log'); Here is my PHP configuration regarding logging functions : error_reporting = E_ALL & ~E_NOTICE display_errors = On display_startup_errors = Off log_errors = On Let's add another strange behaviour. If I add the following line in php.ini : error_log = d:/program files/apache group/apache/logs/error.log and execute again the first example (error_log with 2 args and then header), it works fine :) Any clues ? ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=13932&edit=1
