The difference between both session_unset and session_destroy is as follows: session_unset just clears out the sesison for usage. The session is still on the users computer. Note that by using session_unset, the variable still exists. Using session_unset in tandem with session_destroy however, is a much more effective means of actually clearing out data. As stated in the example above, this works very well, cross browser: session_unset(); session_destroy(); I noticed that in firefox, one could simply use sesison_unset and the session would be cleared. When trying this on IE, I was horrified to find out that the data was still there, so I had to use session destroy. ---- Manual Page -- http://www.php.net/manual/en/function.session-unset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54731 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54731&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54731&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54731&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54731&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54731&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54731&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54731&report=yes Search -- http://master.php.net/manage/user-notes.php
