If the method doesn't exist within the class that the ReflectionClass is reflecting an Exception is thrown.

If you ever need to get the type hint of a parameter in a method use this.

<?php //Target our class $reflector = new ReflectionClass('MyClass'); //Get the parameters of a method $parameters = $reflector->getMethod('FireCannon')->getParameters(); //Loop through each parameter and get the type foreach($parameters as $param) { //Before you call getClass() that class must be defined! echo $param->getClass()->name; } ?>
