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.

To get the most out of this book

This is a book for PHP developers, and the main thing that you need is a way to write and run PHP code. For editing, modern development practices have very much embraced the IDE as an essential tool. Popular IDEs include PhpStorm and NetBeans. You may choose to use a more lightweight code editor, such as VSCode or Sublime Text, if you prefer.

You will need to be able to run PHP 8 code on the command line, and if you want to run the last chapter, then you will need PHP 8.1 as well. Installing PHP is beyond the scope of this book and is dependent on your specific operating system or virtualization technology.

Practically all code samples in this book (excluding very minor snippets) are included in the public Git repository available on GitHub at You are strongly encouraged to clone or download all this code so that you can load it in your IDE, run it, and generally play around with it.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
