Bug description: PHP does not create references to $this
Description:
------------
There is a bug in creating references (This problem does not exist in
PHP5). If you have, for example, two classes and the first class creates
second and passes itself as reference to second's constructor, reference
is not being created. I've been trying to create this reference in many
ways, but always with the same result - there is no reference, only a copy
of class which was passed as reference.
Reproduce code:
---------------
class B {
var $Parent;
function B(&$parent) {
$this->Parent = $parent;
$this->Parent->Data = 'foo';
}
}
class A {
var $Data;
var $B;
function A() {
$this->B = new B($this);
}
}
$a = new A;
echo $a->Data;
Expected result:
----------------
echo should return 'foo', but returns nothing. In php5 it works properly.
Note, that I have used the & operator in B's constructor to create a
reference to A class.
