Overview of this book

PHP has come a long way since its introduction. While the language has evolved with PHP 8, there are still a lot of websites running on a version of PHP that is no longer supported. If you are a PHP developer working with legacy PHP systems and want to discover the tenants of modern PHP, this is the book for you. The Art of Modern PHP 8 walks you through the latest PHP features and language concepts. The book helps you upgrade your knowledge of PHP programming and practices. Starting with object-oriented programming (OOP) in PHP and related language features, you'll work through modern programming techniques such as inheritance, understand how it contrasts with composition, and finally look at more advanced language features. You'll learn about the MVC pattern by developing your own MVC system and advance to understanding what a DI container does by building a toy DI container. The book gives you an overview of Composer and how to use it to create reusable PHP packages. You’ll also find techniques for deploying these packages to package libraries for other developers to explore. By the end of this PHP book, you'll have equipped yourself with modern server-side programming techniques using the latest versions of PHP.

However, I hope you have learned enough to understand some basic concepts and now know how to research and learn more about these topics.

We started by looking at technical debt and how you can avoid this by adopting clean code practices. We briefly touched upon some major topic areas of clean code and particularly the popular acronyms SOLID and DRY, as well KICK, which was purposely created for this book! We talked about naming things clearly and trying to write self-documenting code. We learned about the perils of cyclomatic complexity and the wonders of early returns as a proven method to reduce this. Immutability was the next topic, and we explored some of the perils of mutable classes when working with PHP's "by reference" object variables. The last...
