Object references appear to change every time a change is made to the object, at least under NT. This means that you can't store mutable objects inside an array, for example. This is bad!

<?php

class example {

var $a;

function test() {
	$temp=$this;
	$this->a=10;
	return $temp;
	}

}

$c = new example;
$c->a=1;
$result=$c->test();
print($result->a);

# prints out the number 1, not the number 10!!

?>

There's no concept of references in PHP, even though there
might be in the future (the word 'might' is intentional).

Your example behaves exactly as expected, once you
understand that two variables never point to the same
data (except for one specific case, which is passing by
reference in function calls).
