unsetting object references

Hey, sorry to bother you all but I have another obscure question about objects in PHP (yes I really do care about the answer)... I'm simply wondering if I unset() a reference to an object, whether or not it destroys that object, if there are other references to it that still exist. $_SESSION['object'] = serialize($object); (in another script:) $object = unserialize($_SESSION['object']); // do some stuff with $object unset($object); What's going on with my $_SESSION['object'] ?
