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;

}



?>
