'Load a .env file with PHP

I'm currently coding on a pure PHP project and I need to load an .env file to get some variables. After a bit of searching I turned to the vlucas/phpdotenv plugin (That I imported with Composer), but I can't import it! Do I have to use an MVC model for this to work?

index.php:

<?php
    $dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
    $dotenv->load();

bdd.php:

<?php

    function DBConnect() {
        $user = getenv("DB_USER");
        $pass = $_ENV["DB_PASSWORD"];

You forgot to add require_once realpath(__DIR__ . '/vendor/autoload.php'); to your index.php

.env

USER_NAME='jfBiswajit'

index.php

<?php

require_once realpath(__DIR__ . '/vendor/autoload.php');

// Looing for .env at the root directory
$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();

// Retrive env variable
$userName = $_ENV['USER_NAME'];

echo $userName; //jfBiswajit

v5 has changed even further; Use createUnsafeImmutable in place of createImmutable

The Dotenv\Dotenv::createImmutable and Dotenv\Dotenv::createMutable methods no longer call will result in getenv and putenv being called. One should instead use Dotenv\Dotenv::createUnsafeImmutable and Dotenv\Dotenv::createUnsafeMutable methods, if one really needs these functions.

Here is the guide for upgrading
