Routing
One important aspect of any website is the form of the URLs.
/**
* Front Controller - public/front.php
*
* Following the MVC pattern is not the right goal.
* The main goal should be Separartions of Concerns SoC.
*
* Route configuration moved to its own file (app.php)
* Routes names are used for template names.
*
* Based on $routes information (RouteCollection instance),
* a UrlMatcher instance can match URL paths.
*
* The matched route is automaticaly stored in _route attribute.
* Attributes are extracted to keep template simple.
*
* The request context is not strictly needed,
* but it is used in real-world applications
* to enforce method requirements and more.
*
* ----------------------------------------------------------
*
* composer require symfony/http-foundation
* composer require symfony/routing
*
* php -S localhost:8000 public/front.php
*
* http://localhost:8000/hello/Fabien
* Hello Fabien
* http://localhost:8000/bye
* Goodbye!

App
We separated the configuration specific to our application in app.php
/**
* App Configuration - src/app.php
*/
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;
$routes = new RouteCollection();
$routes->add('hello',
new Route('/hello/{name}', ['name' => 'World'])
);
$routes->add('bye',
new Route('/bye')
);
return $routes;
