Description:
------------
Documentation of get_object_vars says "Note that it will only return parameters defined on that object's class, not on its parent class" (from the https://www.php.net/manual/en/function.get-object-vars.php), but it returns parameters of the parent classes as well.

Test script:
---------------
class A {
    public $aProperty;
}

class B extends A {
    public $bProperty;
}

$b = new B();

var_dump(get_object_vars($b));

Expected result:
----------------
No misleading statement in the documentation
