php - How do I get the type of constructor parameter via reflection?

Question

I'm using type hinting on my constructor parameter list like so:

public function __construct(FooRepository $repository)

Is there a way to use the PHP Reflection API to get the hinted type? In other words, I want a reflection function that I can call to somehow get back the string "FooRepository". I've tried getting the constructor via reflection and then getting the parameters if the constructor, but I don't see anything that will give me the string of the hinted type.

Try this out.

class Foo {
    public function __construct(Bar $test) {
    }
}

class Bar {
    public function __construct() {
    }
}

$reflection = new ReflectionClass('Foo');
$params = $reflection->getConstructor()->getParameters();
foreach ($params AS $param) {
    echo $param->getClass()->name . '<br>';
}
