Symfony - multiple paths to the same route within a controller

I couldn't work out how to use Route Aliasing within my controller. I couldn't find anything in the documentation about it. But, thanks to a StackOverflow comment it is possible.

Suppose you want users to be able to access a page using /users/123 and /people/123 - with both routes displaying the same data?

Normally you'd write something like #[Route('/user/{id}', name: 'show_user')] - as it happens, that first parameter can be an array! Which means you can write:

 PHP<?php

namespace App\Controller;



use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

use Symfony\Component\Routing\Annotation\Route;



class ThingController extends AbstractController

{



    #[Route(["/user/{id}", "/people/{id}", "/guests/{id}"], name: 'show_user')]

    public function show_user(int $id) {

        // Your logic here

    }

}

If you need to know which route your user took, call $request->getRequestUri(); to get the string representation, i.e. /user.
