To copy around a reference you will just use it as a regular value. Like in your second example, i.e.: $same_object = $object; Basically you're just copying the object handle and not the object itself. In order to create a real copy (with a new object handle) you'll do: $new_object = $object->__clone(); Andi -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
