Modular Programming with PHP 7

By: Branko Ajzele

Overview of this book

Modular design techniques help you build readable, manageable, reusable, and more efficient codes. PHP 7, which is a popular open source scripting language, is used to build modular functions for your software. With this book, you will gain a deep insight into the modular programming paradigm and how to achieve modularity in your PHP code. We start with a brief introduction to the new features of PHP 7, some of which open a door to new concepts used in modular development. With design patterns being at the heart of all modular PHP code, you will learn about the GoF design patterns and how to apply them. You will see how to write code that is easy to maintain and extend over time with the help of the SOLID design principles. Throughout the rest of the book, you will build different working modules of a modern web shop application using the Symfony framework, which will give you a deep understanding of modular application development using PHP 7.

Understanding Packagist


The main repository, when it comes to Composer packages, is Packagist (https://packagist.org). It is a web service that we can access through our browser, open an account on for free, and start submitting our packages to the repository. We can also use it to search through already existing packages.

Packagist is generally used for free open source packages, though we can attach privateGitHub and BitBucket repositories to it in the same manner, the only difference being that the private repositories require SSH keys in order to work.

There are more convenient commercial installations of the Composer packager, such as Toran Proxy (https://toranproxy.com). This allows easier hosting of private packages, higher bandwidth for faster package installations, and commercial support.

Up to this point, we sliced our applications into six different Git repositories, one for core application and the remaining five for each module (catalog, customer, payment, sales, and shipment...
