Symfony is a PHP framework, started by the French company SensioLabs. It's an Open Source frameowkr and is maintained by a large online community. This big community is one of the reasons why I chose this framework, but other essential reasons are the ease of use and the high level of flexibility. Together with Symfony I use Doctrine, a library that forms a really useful layer between the code and the database. At the Symfony conference of 2012 in Paris I have successfully taken the Symfony2 certification exam.
