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.

Chapter 4. Requirement Specification for a Modular Web Shop App

Building a software application from the ground up requires diverse skills, as it involves more than just writing down a code. Writing down functional requirements and sketching out a wireframe are often among the first steps in the process, especially if we are working on a client project. These steps are usually done by someone other than the developer, as they require certain insight into client business case, user behavior, and the like. Being part of a larger development team means that we, as developers, usually get requirements, designs, and wireframes then start coding against them. Delivering projects by oneself, makes it tempting to skip these steps and get our hands started with code alone. More often than not, this is an unproductive approach. Laying down functional requirements and a few wireframes is a skill worth knowing and following, even if one is just a developer.
