Last week I needed a small website. I wanted it to be quick and dirty. Well, blazing fast and not so dirty. I heard best about Silex, so I gave it a shot. It was more then good experience. It worked like a charm, it was fun to use and site was completed in one day.
He includes two code snippets - one is the basic "hello world" example that most Silex tutorials reference and the other is more specific to his site. It defines the routes and the (Twig) templates they relate to. A few submodules helped him get this and other functionality working (like the Forms component and Swiftmailer for a contact form). You can find the full source for the site over on github.
