note 21840 added to function.session-unregister

from the documentation... Note: If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable. In fact, unset doesn't have the expected behavior, it only unsets the variable for the execution of a particular script. Use session_unregister to completely erase the variable from the session. -- http://www.php.net/manual/en/function.session-unregister.php http://master.php.net/manage/user-notes.php?action=edit+21840 http://master.php.net/manage/user-notes.php?action=delete+21840 http://master.php.net/manage/user-notes.php?action=reject+21840
