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.

In this chapter, we're going to start by reviewing exactly what Composer and dependency management are all about.

Then, we are going to make sure we understand what autoloading is and how Composer provides us with a fully-featured autoloader that solves class loading once and for all.

Next, we will get into the real reason for using Composer, which is to acquire third-party packages and libraries so that we can easily bring functionality and features into our application, as provided by high-quality third-party libraries.

Once we've looked at how to bring in dependencies, we are going to go over the...
