Bug #18035 Updated: session_destroy causes loss of output

ID: 18035 Updated by: sniper@php.net Reported By: warwick@imvs.sa.gov.au -Status: Open +Status: Feedback -Bug Type: Output Control +Bug Type: Session related Operating System: RedHat 7.2 PHP Version: 4.2.0 New Comment: I can't reproduce this..can you please try this snapshot: http://snaps.php.net/php4-latest.tar.gz Previous Comments: ------------------------------------------------------------------------ [2002-06-28 01:30:24] warwick@imvs.sa.gov.au This problem occurs with PHP 4.2.0 and PHP 4.2.1 but is fine using PHP 4.1.1 and older versions. When calling a session_destroy() on a newly created session, it will clear buffered output when greater than 4k without sending it to the client. The following sample script should demonstrate this. When $repeatCount is 4096 or greater, only the word END will be output, without the 4096 X's preceeding it. When repeatCount is 4095 the X's and the word END are sent. By removing the session_destroy() call following the str_repeat echo the X's will be output regardless of the $repeatCount setting. <?php ## Sample script ## ## Relevant (?) php.ini settings I have: ## output_buffering = Off (have tried 8192 - no effect) ## output_handler = ## zlib.output_compression = Off ## implicit_flush = Off ## $repeatCount = 4095; ## Works fine $repeatCount = 4096; ## Fails session_start(); echo str_repeat('X', $repeatCount); session_destroy(); echo "END"; ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18035&edit=1
