Description:
------------
When extending a class, private member variables from parent class are retained even if child class defines same-named variable. 

Reproduce code:
---------------
<?php 
class A {
	private $a = 'From class A';
} 

class B extends A{
	private $a = 'From class B';
}
echo '<pre>';print_r(new B);echo '</pre>';
?>

Expected result:
----------------
b Object
(
    [a:private] => From class B
)



Actual result:
--------------
b Object
(
    [a:private] => From class B
    [a:private] => From class A
)

This is expected. When a member is private, it can only be 
seen by the class it is a member of. Class B has no idea 
class A also has a member called $a and goes ahead and 
creates one. It's just a matter of visibility.
