PHP Composer is a package dependency management tool for PHP used by developers to manage their PHP-based projects/applications. You probably have seen some PHP applications requiring that you have a composer installed on the system to get the package installed and working.
PHP composer is frequently used to facilitate the installation and update of dynamic PHP applications that need easier management. These packages can easily be installed and managed using the composer dependencies tool.
It maintains a list of required packages in a JSON file called composer.json.

sudo apt-get install python-software-properties sudo add-apt-repository ppa:ondrej/php sudo apt update
Now run the commands below to install PHP 7.2. change the number value to install 7.1, 7.3, and so forth.
sudo apt install php7.2
Install Composer
Now that PHP is installed. You can now run the commands below to install Composer
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
The commands above will download Composer from its maintainer page and install it into the /usr/local/bin directory. This is a local-global directory for application executables.
