Preface

PHP is currently one of the most popular languages in web development. Over time, the language itself has grown and become more mature. However, it still lacks good design patterns and good habits "by design". You can write a very good code with it, but you can also write very bad "spaghetti code".

Symfony2 is currently one of the most popular frameworks to speed up PHP development. It greatly helps you to create clean and reusable code, and it is the first framework that takes modern design patterns like DependencyInjection very seriously. It is also the first framework that uses features of PHP 5.3—namespaces, closures, and so on. By using this framework, you will be able to deliver more advanced and complicated web applications, suitable even for enterprise requirements.
