Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.
PHP (including php-cli)
The installation process of Composer is relatively simple. First, let's get in the good habit of updating our server.
# sudo yum -y update
Switch into the temp directory.
# cd /tmp
Install Composer using cURL
# sudo curl -sS https://getcomposer.org/installer | php
Want to make Composer globally accessible?
# mv composer.phar /usr/local/bin/composer
Composer is an essential tool for any PHP developer. It is very easy to install and you will save countless hours over the years automating your dependencies. Happy developing!
