I'm trying to do this (which produces an unexpected T_VARIABLE error): public function createShipment($startZip, $endZip, $weight = $this->getDefaultWeight()){} I don't want to put a magic number in there for weight, since the object I am using has a "defaultWeight" parameter that all new shipments get if you don't specify a weight.
