No, it's exactly the other way around with objects, you get a slight performance penalty (though it may no be noticeable at all). Currently, not useing the '&' operator will always create a new (shallow) copy of the objects. This is already addressed with the new Zend Engine 2 which will behave as expected (objects aren't copied, they stay atomic until explicitely duplicated [cloned]). - Markus -- GnuPG Key: http://guru.josefine.at/~mfischer/C2272BD0.asc Did I help you? http://guru.josefine.at/~mfischer/wishlist_en Konnte ich helfen? http://guru.josefine.at/~mfischer/wishlist_de
