note 104747 added to class.serializable

You cannot throw an exception inside the serialize() method. This will cause PHP to complain that you are not returning a string or NULL. The best way to prevent the serialization of an object is to throw an Exception in the __sleep() method: <?php class Obj { public function __sleep() { throw new BadMethodCallException('You cannot serialize this object.'); } } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 98.103.79.230 ---- Manual Page -- http://www.php.net/manual/en/class.serializable.php Edit -- https://master.php.net/note/edit/104747 Del: integrated -- https://master.php.net/note/delete/104747/integrated Del: useless -- https://master.php.net/note/delete/104747/useless Del: bad code -- https://master.php.net/note/delete/104747/bad+code Del: spam -- https://master.php.net/note/delete/104747/spam Del: non-english -- https://master.php.net/note/delete/104747/non-english Del: in docs -- https://master.php.net/note/delete/104747/in+docs Del: other reasons-- https://master.php.net/note/delete/104747 Reject -- https://master.php.net/note/reject/104747 Search -- https://master.php.net/manage/user-notes.php
