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.

Design patterns

Now we have had a look at clean code, the next thing to learn about in this chapter is design patterns. As explained previously, these are tried and true code patterns that you can use to solve common problems. They provide well-used structure and nomenclature that makes your code clear in terms of what it does and also provides you with a scaffold to build upon when solving common problems.

Design patterns are generally grouped into four categories. The following sections detail the four categories, with some examples of each. Rather than trying to provide full code examples for each pattern (which would take up way too many pages), I am simply going to describe the pattern and then link to examples within open source code bases. For Model, View, Controller (MVC) and Dependency Injection (DI), we have a chapter dedicated to each.

Creational patterns

Creational patterns are used when creating class instances. These make sense when the process of building or...
