#36079 [Opn->Fbk]: Crash in session encode

ID: 36079 Updated by: tony2001@php.net Reported By: njewell at matrix-data dot co dot uk -Status: Open +Status: Feedback Bug Type: Session related Operating System: Windows XP PHP Version: 5CVS-2006-01-19 (snap) New Comment: Reopen when you have a real reproduce script. Previous Comments: ------------------------------------------------------------------------ [2006-01-19 14:13:21] njewell at matrix-data dot co dot uk I've found the cause. At the end of the code I was doing: foreach ($_SESSION as $key => $values) { unset($_SESSION[$key]); } I've changed this to: foreach (array_keys($_SESSION) as $key) { unset($_SESSION[$key]); } I know that the first loop is probably bad form, but there is (obviously) something breaking deep in PHP anyway. I've been unable to reconstruct a "small" sample as my session is quite big. If I try and replicate it outside of my working code in a small example I can't reproduce it. Sorry - I know that doesn't help much. ------------------------------------------------------------------------ [2006-01-19 10:36:56] sniper@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2006-01-19 10:35:20] njewell at matrix-data dot co dot uk Description: ------------ I am seeing Apache crash upon saving a session.
