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.

This brings us to the end of our first chapter. Let's quickly recap what we have covered. First of all, we explored what the term OOP actually means. We looked at some other programming styles and used this to compare with some OOP code to hopefully highlight the differences. We then had a quick look through some popular PHP OOP projects that are worth looking at in more detail if you would like to see some real-world code and maybe get your hands dirty. Finally, we had a very quick overview of some basic OOP features. You should already know these in detail and so we didn't go over them in any depth – if you do not already know them, then you are encouraged to hit the official docs to fill in the gaps. In the next chapter, we are going to look at some more advanced topics in object-oriented PHP related to the ways that we can orchestrate a graph of related objects, either using inheritance or, alternatively, using composition.
