When I'm triing to use a reference on $this into the constructor of a object, it's a copy of the reference which is passed.

have a look to this sample.

class A
{
 var $value;
 var $pB;

 function A()
 {
  $this->Value = 100;
 }
}

class B
{
 var $value;
 function B(&$aa)
 {
  $this->value = 200;
  $aa->pB = &$this;
 }
}

$aa = new A();
$bb = new B($aa);
$bb->value = 50;

echo var_dump($aa);

there is no 50 in the repr?sentation of the var_dump function.

I've looked in the doc if this limitation is sp?cified, but NO!
