code 2: direct access

$child=new Child();
$child->getFields(new Base());
what is the context of the method? base or child?
the result direct access and get_object_vars must be the same.
it is a bug that the get_object_vars function do not check the method
belongs to, but just check the object class call the method.

Surely Base class can access it's own private properties.
The method belongs to the Base and is executed in it's scope.

but it works expect if the method change to this
function getFields($obj){
return array('p1'=>$obj->p1);
}
and it work expect in java using reflection
think about: Liskov Substitution Principle
i thing this is the implemention bug of get_object_vars

I would be very surprised to be able to access private properties of
Base in the context of Child.
What you see is expected.
