use Silex\Application; $app = new Application();
use Silex\Application; use Silex\Provider\TwigServiceProvider; $app = new Application(); // Add Twig service provider $app->register(new TwigServiceProvider(), array( 'twig.path' => __DIR__ . '/views' ));In these examples, we can see that we are using the Silex\Application class to create a new instance of the application. In Example 2, we are also using the TwigServiceProvider, which is part of the Silex\Twig package library, to add the Twig templating engine to our application. Overall, Silex is a powerful and flexible micro-framework for PHP that provides a simple and efficient way to build scalable and maintainable applications.
