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 covered the metadata configuration in the composer.json file that needs to be sorted so that Packagist or other systems can work correctly. Then we had a quick review of namespaces and source folders and the relevant configuration in composer.json. After this, we looked at how you can configure your package to offer an executable file that will be set up as a symlink when your package is installed. Then we looked again at SemVer and how you should carefully create new releases following a SemVer versioning system so that users of your package (including your own projects) can safely require the versions that they need without getting any unwanted or unexpected breaking changes. With the package complete, we then looked at ways you...
