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 start by creating a new module called Foggyline\SalesBundle. We do so with the help of the console, by running the command as follows:

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

The command triggers an interactive process, asking us several questions along the way, as shown here:

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

new Foggyline\PaymentBundle\FoggylineSalesBundle(),

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

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

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

Creating a Cart entity

Let's go ahead and create a Cart entity. We do so by using the console, as shown here:

php bin/console generate:doctrine:entity

This triggers...
