The Symfony2 framework is on its way for the 2.1 version, which will be the longtime supported version for the next 5 years. In this session, we will introduce the Symfony2 framework by looking at its underlying architecture based on standalone and decoupled components, and the MVC implementation. Then, we will focus on the most interesting features that Symfony provides out of the box to help developers be more productive and efficient in their day to day work. These features include cascading configuration, database abstraction layer, forms management, HTTP caching, unit and functional testing and security (authentication & authorization).
