Quickly what is PHP Composer?

PHP Composer is a dependency manager for PHP. With this dependency manager, you will be able to manage the libraries that your web application requires.

One of the examples where the usefulness of Composer is best shown is when our project depends on many external libraries. Thanks to Composer, we will be able to add them, to eliminate them and to update them in a fast and simple way.

The operation of PHP Composer is quite similar to the one we give to the package managers for Linux, like APT or DNF.

So, we need a tool that can be used to install libraries and manage PHP application dependencies. And for that, it is better than PHP Composer. Let’s go for it.

After the dependencies are installed in the system, we can download the PHP Composer installer to our system without any problems.

Now, it is necessary to use the wget command to download PHP Composer.

wget https://getcomposer.org/installer -O composer-installer.php

Now perform the installation by running the following command

sudo php composer-installer.php --filename=composer --install-dir=/usr/local/bin

You will get an output screen like the following;
