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;
}

?>
