codeigniter3 integrates composer management tools

Preface, I hope codeigniter4 will be released soon. There is also codeigniter3 for projects. I want to use so many excellent third-party libraries on github. What should I do? Moreover, these libraries are basically installed through composer. The following introduces the method of integrating the composer package manager:

1. Install composer, which I won’t go into details.

2. Create a new composer.json file in the project root directory. For example, I want to use a jwt library in ci now

{
  "require": {
    "firebase/php-jwt": "*"
  }
}

3. Execute the command line in this directory: composer install

Or the above 2 steps can be simplified into the following step

composer require firebase/php-jwt

4. Let’s start the formal integration into ci. There are 2 methods here:

Method 1: Simple and crude (not Recommended)

require_once './vendor/autoload.php';
//上面这一行添加到index.php的这个位置
require_once BASEPATH.'core/CodeIgniter.php';

Method 2: Elegant (recommended)

application/librariesCreate a new MY_Composer.php

<?php
/**
 * 关于MY_Composer的注释
 *
 * @author 新猪
 */
class MY_Composer 
{
    function __construct() 
    {
        include("./vendor/autoload.php");
    }
}

and then modify it in config/autoload.php

$autoload['libraries'] = array('MY_Composer','database','session');

5. Finished using

<?php
use \Firebase\JWT\JWT;
class TestController extends CI_Controller {
    public function index() {
        $key = "example_key";
        $token = array(
            "iss" => "http://example.org",
            "aud" => "http://example.com",
            "iat" => 1356999524,
            "nbf" => 1357000000
        );
        $jwt = JWT::encode($token, $key);
        $decoded = JWT::decode($jwt, $key, array(&#39;HS256&#39;));
        print_r($decoded);
    }
}

, I hope it will be helpful to everyone.
