In 2013, 1 out of every 10 PHP developers were using Symfony. If you ask me, that sounds like not much from the initial impression. But if we sum up the most used frameworks on that language on these days, we could probably reach a number above 30. That shows the real adoption rate for Symfony between web application developers. With almost 1,000 contributors, Symfony is not just a framework, but a Philosophy and a Community.

In this book, I intent to provide a large variety of tips, advices and even patterns for building enterprise level web applications with Symfony. You will learn how to write low coupling, well-tested and SOLID code inside this amazing framework, in order to achieve the maximum quality in terms of code design for your software.
