Front

 
/**
 * Front Controller - front.php
 * 
 * Until now our application has only one page.
 * Let's extract the common code and create the framework.
 * 
 * The trick is the usage of Request::getPathInfo() which ...
 * removes the front controller script name.
 * 
 * composer require symfony/http-foundation
 * php -S localhost:8000 front.php
 * 
 * http://localhost:8000/hello
 *      Hello World
 * http://localhost:8000/bye
 *      Goodbye!
 * http://localhost:8000/front.php
 *      Page not found
