Class Firebase\JWT\JWT not found

I want to use pure firebase/php-jwt library in my code. Firstly, I go to /var/www/html/ and like the official library page is suggesting, I do this

composer require firebase/php-jwt

After I run this command, I see that a new vendor folder is created inside /var/www/html/ with a lot of files and subfolders. I then create my token.php file right in /var/www/html/ with contents similar to that from the official page:

<?php
use \Firebase\JWT\JWT;

$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('HS256'));

print_r($decoded);

However, when I go to localhost/token.php, I get this error message:

Fatal error: Uncaught Error: Class 'Firebase\JWT\JWT' not found in /var/www/html/token.php:12 Stack trace: #0 {main} thrown in /var/www/html/token.php on line 12

I'm not sure if it matters, but my PHP version is 7.0.

As per the documentation, you need to include the autoloader.

E.g., in your php file:

require __DIR__ . '/vendor/autoload.php';

But... typically your vendor folder would be at the same level than your html folder (the one where you are serving content).

E.g.:

- Project root
--- vendor
--- html
----- index.php

Then in your index.php you'd do:

 require __DIR__ . '/../vendor/autoload.php';

It is nice that you trying to use composer and modules, but if I were you I'd try to read on a bit about php's autoloading features, so you understand what's going on, and how you can profit from them.
