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.

Private Git repos as Composer dependencies

You would be forgiven for thinking that you must release a package on Packagist if you want to be able to use it as a Composer package with your other projects. This is definitely not the case, and for those little packages that you would prefer to keep completely private, you should definitely use this trick.

You can share your Composer package privately among your own projects by simply having it accessible on a version control system (VCS), such as Git. The most popular publicly accessible implementation of Git is undoubtedly GitHub, though there are many other choices, including hosting your own private repositories on your own server.

In the projects where you want to use this shared library, you must add a little extra JSON config to instruct Composer that it needs to go and query this specific repository.

The best place to learn about this technique is on the official docs page:
