object reference

[Anon]

How can i pass an object to an other object witout creating a copy?

what i men:

$object1 = new object1();

$object2 = new object2($object1);

$object2->parent should be a reference to object1 stored in object2.
I don´t want to use global vars.
if the way i want to use works i can manipulate $object1 using then local reference within $object2.

i´m using php4.0.3 on win98se

class object2 {
var $parentNode;
function object2(&$parentObject) {
$this->parentNode = &$parentObject
}
}

The & means pass by reference, not by value.
