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.

Executable Binaries Configured under bin

It is quite common for a person to want to provide some kind of executable with their Composer package.

You will probably have noticed that, when installing some packages, Composer not only creates the source folders and files under vendor but also creates a bin or vendor/bin directory (depending on how you have things configured) that contains all the executable files that your dependencies provide.

It is definitely worth reading the official documentation on this:

https://getcomposer.org/doc/articles/vendor-binaries.md

For our HelloWorld package, we have an executable defined that provides the mission-critical functionality of our package:

composer-module-hello-world/bin/hello

Repo: https://git.io/JRw5R

#!/usr/bin/env php
<?php
declare(strict_types=1);
/**
 * Handle the fact that you may be executing this from your own package,
