Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Yes, class design has to be well thought. Previous Comments: ------------------------------------------------------------------------ [2010-08-26 12:14:10] dev dot php at linke-t dot net Description: ------------ i the case of class "B" extends a class "A" wich define the function __sleep(), instances of class "B" would class A::__sleep. In this case class serialzing would be very buggy - i tried something like: Try: let return the __sleep of class "A" all propertys wich are currently definied resoulting Problem: private properety of class "B" are null or NAN Try: define the function __sleep() in class "B" resoulting Problem: private properety of class "A" are null or NAN Test script: --------------- class A{ public $A_A = 10; protected $A_B = 11; private $A_C = 12; public function A(){ } private function __sleep(){ echo "sleep of A()"; if(get_class($this) != "A") { $d = array_keys( get_class_vars(get_class($this))); return ($d); } return array("A_A","A_B","A_C"); } public function __get($v){ return "PR"; } } class B extends A{ public $B_A = 20; protected $B_B = 21; private $B_C = 22; public function B(){ $this->A(); } public function __sleep(){ return array("A_A","A_B","A_C","B_A","B_B","B_C"); } /* remove this __sleep would let php use A::__sleep() } $a = new A(); $b = new B(); echo "<br/>A"; echo "<br/>" . htmlspecialchars(serialize($a)); echo "<br/>B"; echo "<br/>" . htmlspecialchars(serialize($b)); Expected result: ---------------- the complettely serialized Object like with out __sleep()! Actual result: -------------- private propertys of parent or child are null or NAN with defined __sleep() ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52706&edit=1
