Composer is a must-have tool for every PHP developer these days. This page is a simple breakdown of quick-install instructions.
## How do I install composer?
1. Use PHP to download the composer installer, place it in the current directory, and name it `composer-setup.php`
2. Use PHP to check the hash of the file you downloaded and compare it to the known value of the hash. You can always find the current value of the hash for the installer on the [Composer Public Keys / Signatures](https://composer.github.io/pubkeys.html) page.
3. Run the setup program to install composer. This does more than just download the latest copy of composer, it also sets up your local ~/.composer directory. This will install composer into the current directory. You can add the --install-dir=DIR to specify where you want composer installed. You can also specify --filename=composer to chang ethe installed filename. You can use anything you like that doesn’t already exist in y...
PHPUnit is an essential tool for every PHP developers. It is one of those tools that every PHP developer should have installed in their development environment. The problems most first time PHPUnit developers run into are where to install it and how to install it. This quick guide will walk you through the process and answer both questions.
## How do I install PHPUnit
### The Easy Way
In your project’s root directory use this command.
`composer require --dev phpunit/phpunit ^6.0`
This command adds PHPUnit to your project as a development dependency. This is the absolute best way to install PHPUnit. It is the best way because this way the version of PHPUnit does not change unless you change it. We specified ^6.0 as the version which means we’ll get all the updates to the 6.0 branch but not 6.1. While BC breaks don’t happen often in PHPUnit, they have happened. If you have a globally installed version of PHPUnit and you upgrade ...
Composer is the way that that PHP developers manage libraries and their dependencies. Previously, developers mainly stuck to existing frameworks. If you were a Symfony developer, you used Symfony and libraries built around it. You didn’t dare cross the line to Zend Framework. These days however, developers focus less on frameworks, and more on the libraries they need to build the project they are working on. This decoupling of projects from frameworks is largely possible because of Composer and the ecosystem that has built up around it.
Like PHP, Composer is easy to get started in, but complex enough to take time and practice to master. The Composer manual does a great job of getting you up and running quickly, but some of the commands are involved enough so that many developers miss some of their power because they simply don’t understand.
I’ve picked out five commands that every user of Composer should master. In each section I give you a little ins...
