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;
}
?>
