ID: 35940 User updated by: cristic at interaktonline dot com Reported By: cristic at interaktonline dot com Status: Open Bug Type: Apache related Operating System: Windows XP PHP Version: 5CVS-2006-01-09 (snap) New Comment:
Now I am able to understand better the problem after studying the manual. http://www.php.net/virtual " To run the sub-request, all buffers are terminated and flushed to the browser, pending headers are sent too." This means that the headers are sent to the browser when virtual() is used. Now, my code from the a.php beeing: <?php virtual('/b.php'); ?> <?php header('Location:c.php'); ?> The normal PHP error message should be on both Linux and Windows machines: Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/a.php:1) in /var/www/html/a.php on line 2 Windows Bug: Right now the PHP on Windows crashes (by seeing the trace), I suppose, when tries to get the line number either where the headers were sent or where the Warning is generated. Linux Bug: The error line that is reported to generate the Warning is 0 instead of the line where the header() statement is used meaning line 2.
