Preface

Building modular applications is a challenging task. It involves a wide spectrum of knowledge, ranging from design patterns and principles to the ins and outs of the chosen technology stack. The PHP ecosystem has quite a selection of tools, libraries, frameworks, and platforms to assist us with our goal of modular application development.

PHP 7 brings a lot of improvements that can further assist achieving that goal. We will start our journey by looking into some of these improvements. By the end of this book, our final delivery will be a modular web shop application built by the Symfony framework.
