Smart Routes: GET-only & Validate {Wildcards}

Challenge #1 of 1

Q:
Check out this route: `#[Route('/api/articles/{id}')]`.

How could we best guarantee that the `{id}` part of the URL is a number?

#[Route('/api/articles/{id}']
public function someMethod(int $id)
{
}

#[Route('/api/articles/{id}']
public function someMethod($id)
{
    if (!is_numeric($id)) {
        throw $this->createNotFoundException();
    }
}

#[Route('/api/articles/{<\id+>}']

#[Route('/api/articles/{id<\d+>}']
