Installation Composer

Download setup file:

HASH='curl -sS https://composer.github.io/installer.sig'

Now run the following PHP code to check if the installation script can be executed safely:
php -r "if (hash_file('SHA384', 'composer-setup.php') === '$HASH') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

If the installer is verfied, run the setup script:
sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

Test your installation:
composer --version
