Ensuring an application source code quality is not an easy task. This is especially true with the PHP language, which is still compared to a non-professional programming language nowadays. In fact, the PHP language has plenty of professional tools for monitoring the quality of PHP projects. These tools are also standard enough to be coupled and to communicate with other professional tools in Java for example. In this session, we will introduce some of the Symfony2 best practices to adopt to write clean and maintainable code. Then, we will look at the best PHP quality tools to setup to monitor a Symfony2 project on a day-to-day development. The conference will especially focus on the Jenkins continuous integration platform, automated tests (unit and functional testing) and how to get and interpret metrics on the code.
