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;
}

?>

if you ever need to get the body of a method, use this extension (https://github.com/sagittaracc/reflection):

namespace sagittaracc\classes;

class Test
{
public function method()
{
if (true) {
return 'this method';
}

return 'never goes here';
}
}

$reflection = new ReflectionClass(Test::class);
$method = $reflection->getMethod('method');
echo $method->body; // if (true) { return 'this method'; } return 'never goes here';
