How to use composer

Composer is a dependency management tool for PHP. It allows you to declare the code libraries your project depends on and install them in your project for you based on the declared dependencies. Composer is not a package management tool, because the real packages are located on packagist and github. Composer is equivalent to an intermediate medium to help you install the packages you declare, so composer is a dependency management tool.

How to use composer:

1. First create composer. json file

2. Then execute composer install to install the dependency package

3. Introduce dependencies into the php file, require vendor/autoload.php

Note:

You don’t need to create a composer.json file here. You can install dependent packages directly through composer require supplier/package name. This is also recommended, as it is more convenient.
