note 83517 added to language.oop.magic-functions

To serialize private or protected properties, you need to add the classname to the name of the property (otherwise serialize() will return empty properties): <?php // Works: class SerializeMe { private $myPrivateProperty; public function __sleep () { return array ("\0".__CLASS__."\0"."myPrivateProperty"); } } ?> It looks stupid: Without any __sleep() method private Properties are serialized as well as protected and public. But if you add a __sleep() method, they won't. This may help you saving some hours of googleing ;-) ---- Server IP: 212.124.37.9 Probable Submitter: 217.86.142.15 ---- Manual Page -- http://www.php.net/manual/en/language.oop.magic-functions.php Edit -- https://master.php.net/note/edit/83517 Del: integrated -- https://master.php.net/note/delete/83517/integrated Del: useless -- https://master.php.net/note/delete/83517/useless Del: bad code -- https://master.php.net/note/delete/83517/bad+code Del: spam -- https://master.php.net/note/delete/83517/spam Del: non-english -- https://master.php.net/note/delete/83517/non-english Del: in docs -- https://master.php.net/note/delete/83517/in+docs Del: other reasons-- https://master.php.net/note/delete/83517 Reject -- https://master.php.net/note/reject/83517 Search -- https://master.php.net/manage/user-notes.php
