Thank you for the report, and for helping us make PHP better. Have a look at interface serializable in 5.1 Previous Comments: ------------------------------------------------------------------------ [2005-09-22 10:45:30] [EMAIL PROTECTED] This code (with __sleep() removed) works perfecty fine: <?php class A { private $a; public function getA() { return $this->a; } public function setA($a) { $this->a = $a; } } class B extends A { } $b = new B(); $b->setA(10); $bSerialized = serialize($b); $bUnserialized = unserialize($bSerialized); var_dump($b); var_dump($bUnserialized); ?> Is this what you need? ------------------------------------------------------------------------ [2005-09-22 07:00:26] ectsue at gmail dot com Description: ------------ I believe that the way serialization works for objects doesn't make sense. I have a subclass whose superclass contains a private member variable. Upon serialization, I cannot get the private member variable to serialize for the subclass (except by using a "NUL class-name NUL member-name" string in __sleep()). Imho, subclasses shouldn't have to know what parts of their parent classes to serialize. I can think of two possible solutions to this problem: 1. Have serialize() walk the inheritance tree for the object it is serializing. 2. Have some method that will be able to take the output from parent::__sleep() and modify it so that it can be passed back from the __sleep() method of the subclass so that private member variables in the parent can be serialized. (The function I have in mind would do the NUL class-name NUL member-name transformation). Reproduce code: --------------- class A { private $a; public function __sleep() { return array('a'); } public function getA() { return $this->a; } public function setA($a) { $this->a = $a; } } class B extends A { } $b = new B(); $b->setA(10); $bSerialized = serialize($b); $bUnserialized = unserialize($bSerialized); var_dump($b); var_dump($bUnserialized); Expected result: ---------------- object(B)#1 (1) { ["a:private"]=> int(10) } object(B)#1 (1) { ["a:private"]=> int(10) } Actual result: -------------- object(B)#1 (1) { ["a:private"]=> int(10) } object(B)#2 (2) { ["a:private"]=> NULL ["a"]=> NULL } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34593&edit=1
