note 103936 added to class.serializable

You can prevent an object getting unserialized by returning NULL. Instead of a serialized object, PHP will return the serialized form of NULL: <?php class testNull implements Serializable { public function serialize() { return NULL; } public function unserialize($data) { } } $obj = new testNull; $string = serialize($obj); echo $string; // "N;" ?> That's perhaps better than throwing exceptions inside of the serialize function if you want to prevent serialization of certain objects. ---- Server IP: 69.147.83.197 Probable Submitter: 79.225.61.4 ---- Manual Page -- http://www.php.net/manual/en/class.serializable.php Edit -- https://master.php.net/note/edit/103936 Del: integrated -- https://master.php.net/note/delete/103936/integrated Del: useless -- https://master.php.net/note/delete/103936/useless Del: bad code -- https://master.php.net/note/delete/103936/bad+code Del: spam -- https://master.php.net/note/delete/103936/spam Del: non-english -- https://master.php.net/note/delete/103936/non-english Del: in docs -- https://master.php.net/note/delete/103936/in+docs Del: other reasons-- https://master.php.net/note/delete/103936 Reject -- https://master.php.net/note/reject/103936 Search -- https://master.php.net/manage/user-notes.php
