Symfony Routing in PHP

Question

I want to set a default value for city to "ABC", how can I do that in this code? Also, are there any examples for me to add multiple routes to this collection?

<?php

use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\Route;

$collection = new RouteCollection();

$collection->add('hello_world_first_homepage', new Route('/weather/{city}', array(
    '_controller' => 'HelloWorldFirstBundle:Default:index',
)));

return $collection;

As defined here, the Route constructor take as a second parameter an array of default values.

You can then add 'city' => "ABC' to the array you're using to intitialize your new route.
