How to install php composer in Linux
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.
We can install it using curl.
#curl -sS https://getcomposer.org/installer | php
If we need to make composer globally accessible,
#mv composer.phar /usr/local/bin/composer
That's all......
