Mastering PHP Design Patterns

By: Junade Ali

Overview of this book

Design patterns are a clever way to solve common architectural issues that arise during software development. With an increase in demand for enhanced programming techniques and the versatile nature of PHP, a deep understanding of PHP design patterns is critical to achieve efficiency while coding. This comprehensive guide will show you how to achieve better organization structure over your code through learning common methodologies to solve architectural problems. You’ll also learn about the new functionalities that PHP 7 has to offer. Starting with a brief introduction to design patterns, you quickly dive deep into the three main architectural patterns: Creational, Behavioral, and Structural popularly known as the Gang of Four patterns. Over the course of the book, you will get a deep understanding of object creation mechanisms, advanced techniques that address issues concerned with linking objects together, and improved methods to access your code. You will also learn about Anti-Patterns and the best methodologies to adopt when building a PHP 7 application. With a concluding chapter on best practices, this book is a complete guide that will equip you to utilize design patterns in PHP 7 to achieve maximum productivity, ensuring an enhanced software development experience.

Preface

Prototype pattern


The Prototype design pattern allows us to effectively duplicate objects while minimizing the performance impacts of having to re-instantiate an object.

You may have heard of prototypal languages if you've worked with JavaScript. In such languages, you work by cloning prototypal objects to create new objects; in turn, there is a reduced cost for creating new objects.

We have, so far, extensively discussed the use of the __construct magic method, but we haven't touched on the __clone magic method. The __clone magic method is what's run before an object is cloned (if possible); the method cannot be called directly and takes no parameters.

You might find it useful to use the __clone method when using this design pattern; that said, you might not need it depending on your use-case.

It's very important to remember that when we clone an object, the __construct function is not re-run. The object has already been constructed so PHP sees no reason to re-run it, so it's worth avoiding...
