I believe Zeev just fixed this (at least your test case works for me). ------------------------------------------------------------------------ [2002-08-08 08:33:16] andre@switch.no Final note; we're currently running with register_globals on, while we migrate old code. It seems that this is the reason unset($_SESSION['varname']) won't work. But, the inconsistent behavior (you can assign to $_SESSION but not unset variables from it), is simply intolerable. Either both: $_SESSION['varname'] = 'value'; unset($_SESSION['varname']); work as intended, even with register globals on, or none of them should work. I would prefer them both to work because this will make it much easier to migrate old code while still running with register globals on. ------------------------------------------------------------------------ [2002-08-08 05:18:43] andre@switch.no unset.php should be the name you save the testscript as... ------------------------------------------------------------------------ [2002-08-07 15:45:01] kalowsky@php.net Your (andre@switch.no) sample script does not work for me. Results look like: session just after session_start() Array ( ) Next and the Next link unset.php doesn't exist. Can you finish your test case please? ------------------------------------------------------------------------ [2002-08-07 10:29:15] andre@switch.no I have the same problem, running 4.1.1 on FreeBSD, put this script somewhere at your site and run it: session_start(); echo '<h2>Session just after session_start()</h2>'; echo '<pre>'; print_r($_SESSION); echo '</pre>'; if(isset($_GET['set'])) { $_SESSION['foo'] = 'bar'; echo '<h2>Session after $_SESSION[\'foo\'] = \'bar\'</h2>'; echo '<pre>'; print_r($_SESSION); echo '</pre>'; } if(isset($_GET['unset'])) { unset($_SESSION['foo']); echo '<h2>Session after unset($_SESSION[\'foo\'])</h2>'; echo '<pre>'; print_r($_SESSION); echo '</pre>'; } if($_GET['step'] == 0) { echo '<a href="unset.php?step=1&set=1">Next</a>'; } if($_GET['step'] == 1) { echo '<a href="unset.php?step=2">Next</a>'; } if($_GET['step'] == 2) { echo '<a href="unset.php?step=3&unset=1">Next</a>'; } if($_GET['step'] == 3) { echo '<a href="unset.php?step=4">Next</a>'; } if($_GET['step'] == 4) { echo '<p>$_SESSION should be an empty array at this point!</p>'; } ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
