Dotenv Component

Symfony Dotenv parses .env files to make environment variables stored in them accessible via $_SERVER or $_ENV.

Getting Started

composer require symfony/dotenv

Usage

For an .env file with this format:

YOUR_VARIABLE_NAME=my-string

use Symfony\Component\Dotenv\Dotenv;

$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/.env');

// you can also load several files
$dotenv->load(__DIR__.'/.env', __DIR__.'/.env.dev');

// overwrites existing env variables
$dotenv->overload(__DIR__.'/.env');

// loads .env, .env.local, and .env.$APP_ENV.local or .env.$APP_ENV
$dotenv->loadEnv(__DIR__.'/.env');

// Usage with $_ENV
$envVariable = $_ENV['YOUR_VARIABLE_NAME'];

// Usage with $_SERVER
$envVariable = $_SERVER['YOUR_VARIABLE_NAME'];
