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.

Implementation


We will start off by creating a new module called Foggyline\ShipmentBundle. We will do so with the help of the console by running the following command:

php bin/console generate:bundle --namespace=Foggyline/ShipmentBundle

The command triggers an interactive process, which asks us several questions along the way, shown as follows:

Once done, files app/AppKernel.php and app/config/routing.yml are modified automatically. The registerBundles method of an AppKernel class has been added to the following line under the $bundles array:

new Foggyline\PaymentBundle\FoggylineShipmentBundle(),

The routing.yml file has been updated with the following entry:

foggyline_payment:
  resource: "@FoggylineShipmentBundle/Resources/config/routing.xml"
  prefix:   /

In order to avoid colliding with the core application code, we need to change prefix: /into prefix: /shipment/.

Creating a flat rate shipment service

The flat rate shipment service is going to provide the fixed shipment method that our sales...
