With the increasing complexity and scale of web applications, dependency management and dependency injection have become an indispensable part of modern web development. The benefit of using Composer is that it can better manage project dependencies and maintain their Updates, while also allowing easy installation, update, uninstallation and management of dependencies within the project.

This article will introduce how to use Composer to manage dependencies in ThinkPHP6.

1. Install Composer

First, you need to install Composer locally. Go to the official website (https://getcomposer.org/) to download and install composer. After the installation is complete, you can use the composer command on the command line to manage php project dependencies.

2. Create a new project

Use composer to create a new ThinkPHP6 project:

composer create-project topthink/think myproject
cd myproject

3. Add dependencies

In composer, use a library, the library needs to be added to the composer.json file in order for composer to download and install it. There are two ways to add dependencies in ThinkPHP6 projects.

1. Manually edit the composer.json file

Open the composer.json file and add the required dependencies. The example is as follows:

{
    "require": {
        "monolog/monolog": "^2.0",

    }
}

composer install

. After the installation is complete, we can reference these libraries in the project.

composer require monolog/monolog

This will automatically update the composer.json file and install the monolog library. Use the composer remove command to remove dependencies from composer.json and delete them from the project.

composer remove monolog/monolog

4. Automatically load dependencies

Composer can also easily access newly added dependencies through the automatic loading mechanism. In the ThinkPHP project, just add the autoload file path to the autoload_files configuration file and we can use the added dependencies.

Modify the config/app.php file and add the following code to autoload_files:

<?php

return [
    //省略其他配置
    'autoload_files'   => [__DIR__ . '/../vendor/autoload.php'],
];

After that, we can use these newly added dependent libraries in the project.

5. Summary

This article mainly introduces how to use Composer to manage dependencies and automatically load dependencies in ThinkPHP6.
