New Comment:
$this is a special variable and is processed differently than other
variables.
Creating references to it simply won't work the way you're expecting it
to.

Description:
------------
When setting reference to $this object, using "=&" operator in a class
method doesn't seem to work as expected (or my understanding is
completely wrong). When unsetting object outside of the class methods -
link breaks and won't unset the referenced objects.
Reproduce code:
---------------
<?php
class uu
{
public $ref;
public function set_me_as_ref(uu &$whom)
{
$whom->ref = &$this;
}
}
$obj1 = new uu();
$obj2 = new uu();
$obj2->set_me_as_ref($obj1);
$obj2 = null; // this won't unset $obj1->ref, but unsets only $obj2
object
// $obj1->ref = null; // this won't unset the $obj2 object, but unsets
only $obj1->ref
echo '<pre>';
var_dump($obj1, $obj2);
?>
Expected result:
----------------
$obj1->ref is supposed to be null
$obje2 - is supposed to be null
Actual result:
--------------
$obj1->ref => living object
$obj2 => null
