Bug Type: Bug
Bug description:__sleep inhertiance
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()
