The Symfony Framework is well-known for being really flexible and is used to build micro-sites, enterprise applications that handle billions of connections and even as the basis for other frameworks. Since its release in July 2011, the community has learned a lot about what's possible and how to do things best. These community resources - like blog posts or presentations - have created an unofficial set of recommendations for developing Symfony applications. Unfortunately, a lot of these recommendations are unneeded for web applications. Much of the time, they unnecessarily overcomplicate things and don't follow the original pragmatic philosophy of Symfony.
