I've mentioned before that I think PHP 5's object thingummies should be referred to as "handles" (and I'm sure I actually saw this usage in early versions of the PHP 5 or Zend Engine 2 proposals). Then, it's much clearer that: $obj2 = $obj1 gives you a copy of the object handle, but: $obj2 = &$obj1 gives you a reference to the handle. Cheers!
