note 62136 added to function.setcookie

I have spent the last, oh 6 months on this- and finally found a simple solution! =) If you can't seem to delete a COOKIE no matter what you try, set your cookie value to a symbol (ie. %) on the logout page. Then on the pages you want to protect, do a ctype_alnum(cookie) check. ie. if( !ctype_alnum(cookie) ) { header("Location: http://www.example.com/logout.php"); } Hope this helps for the people who haven't been able to delete their cookie, or set it to "", 0, FALSE, NULL etc... ---- Server IP: 216.194.113.175 Probable Submitter: 24.147.62.158 ---- Manual Page -- http://www.php.net/manual/en/function.setcookie.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+62136 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+62136&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+62136&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+62136&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+62136&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+62136&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+62136&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+62136&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+62136&report=yes Search -- http://master.php.net/manage/user-notes.php
