I really don't think that is the problem... Im pretty sure i know exactly whats going on.. if you look at the zend_execute it automatically adds a is_ref = 1; and a ref_count++; for all method calls( the comment next to this line says /* for $this ref */.. this works normally just becuase a normal method call is a IS_TMP_VAR.. but in the case of a object's member it is a IS_VAR.. so the ref_count and is_ref gets kept right along with the instance of the object.. so when you try and copy it with $a_copy = $a; the ref gets copyed along with it so changing anything in $a_copy->some_object_you_have_called_a_method_on; the change will be reflected in $a and $a_copy. This is defintly a BUG in engine1 and i think it should be addressed. this bug only happens when you invoke a method from a instance of an objects member that is an object. I looked thru the bugs and found a simmlar bug... - Brad.. __________________________________________________ Do You Yahoo!? Yahoo!
