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.

Description:
------------
method to get the private properties of the base object
in base class object, everything ok
in child class use inherit method, get empty

Reproduce code:
---------------
class Base {
  private $p1='sadf';

  function getFields($obj){
    return get_object_vars($obj);
  }
}

class Child extends Base { }

$base=new Base();
print_r($base->getFields(new Base()));
$child=new Child();
print_r($child->getFields(new Base()));

Expected result:
----------------
Array ( [p1] => sadf )Array ( [p1] => sadf )

--------------
Array ( [p1] => sadf ) Array ( )
