Installing composer on Ubuntu

Well I would rather keep it simple and straight to the point in giving the steps.  These are the steps that you can follow one by one to Install Composer on Ubuntu 14.04

    me@my-ubuntu:/var/www/html$ php -r "readfile('https://getcomposer.org/installer');" > composer-setup.php

    me@my-ubuntu:/var/www/html$ php -r "if (hash('SHA384', file_get_contents('composer-setup.php')) === '41e71d86b40f28e771d4bb662b997f79625196afcca95a5abf44391188c695c6c1456e16154c75a211d238cc3bc5cb47') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

    me@my-ubuntu:/var/www/html$ php composer-setup.php --install-dir=/usr/local/bin --filename=composer

    me@my-ubuntu:/var/www/html$ sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

    me@my-ubuntu:/var/www/html$ php /usr/local/bin/composer

    me@my-ubuntu:/var/www/html/google-analytics$ composer require google/apiclient:1.*

That's it ! You are ready with Composer on your machine.
