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.

First, we're going to explore the Standard PHP Library SPL for short. This is a collection of built-in classes, interfaces, and functions that provide some highly useful functionality and are guaranteed to be available in your PHP installation.

Next up, we're going to take a look at exceptions and error handling in general. We're going to learn what exceptions are and how we can use them to provide safety and easier debugging for our projects.

Finally, we're going to dip our toes into the mystical and powerful world of meta-programming. This is going to introduce you to the awesome power of reflection, and you will learn how it can empower you to regard code as data and thereby increase your power as a programmer dramatically.

This chapter will cover the following main topics:
