If you aren't checking your variables using the 'isset' function, I would suggest not using the unset function for removing values from global variables such as $_SESSION. Save yourself the grief and just say: <?php $_SESSION = null; // to remove (set to null) everything for the session // or $_SESSION['somename'] = null; // to just remove individual session name values whether it is an array or whatever ?> ---- Server IP: 216.194.113.175 Probable Submitter: 152.2.168.205 ---- Manual Page -- http://www.php.net/manual/en/function.unset.php Edit -- https://master.php.net/note/edit/70178 Del: integrated -- https://master.php.net/note/delete/70178/integrated Del: useless -- https://master.php.net/note/delete/70178/useless Del: bad code -- https://master.php.net/note/delete/70178/bad+code Del: spam -- https://master.php.net/note/delete/70178/spam Del: non-english -- https://master.php.net/note/delete/70178/non-english Del: in docs -- https://master.php.net/note/delete/70178/in+docs Del: other reasons-- https://master.php.net/note/delete/70178 Reject -- https://master.php.net/note/reject/70178 Search -- https://master.php.net/manage/user-notes.php
