A possible solution would be to force the conversion with type casts, but I don't see a real advantage in using (int) $obj1 over $obj1->toInt() where the latter is a normal user defined method. Another problem is that such automatic casting from objects to scalars might obscure the code. -- Christoph M. Becker
