In this series you will learn about how to manage PHP projects dependencies using composer.
In modern PHP development composer has become an indispensable tool
that has aided the rapid development of PHP Language.
Composer is a dependency manager for PHP (a tool used for installing, updating and managing libraries that your project depends on).
It is used in almost all modern PHP frameworks such as Symfony, CakePHP and Laravel and composer is one of the most highly recommended tools that solves fundamental issues in many web projects.
Some problems that Composer solves includes:
Resolving dependencies for PHP packages
autoloading solution for PHP packages
keeping all packages updated
Most PHP packages are built on top of other well known PHP packages, a common example are symfony components which forms the bedrock for many PHP frameworks such as Laravel. By using Composer developers can reuse stable PHP libraries and Composer will automatically handle dependency resolution. When you install a package, it will automatically install all the required dependencies for you.
Some of the benefits of using Composer includes:
Quickly integrate libraries from vendors such as AWS, Stripe, Pusher, Algolia, and many others.
Ability to use ready made packages that solve common problems. You need a validation package? search for validation on packagist and get started right away. You need to handle date? Search for Carbon on packagist and get started right away.
Autoload all your files and classes using Composer’s autoload
keeping all packages updated
Composer is an amazing tool that greatly speed up the development of PHP projects. Ready to take your PHP SKILLS to the next level?

In this video I'll give a brief overview of the package that we will be creating and reorganize the current working directory.
In this lecture you will learn how to create a library class.
We are now ready to test the library that we created previously
In this lecture you will learn how to put together a composer dot json file that will be accepted on packagist.org
We are now ready to push the library to GitHub, let create a repository and setup things.
In this lecture we shall submit the package to packagist.org and setup auto update so that changes made to the library will be updated immediately on packagist.org.
Let add some description and usage guide to the readme file so that other developers can easily understand how to use the package.
