Usage ----- [](#usage) ``` use Lazervel\Dotenv\Dotenv; require 'vendor/autoload.php'; ``` If already .env file existing on current directory ``` $dotenv = Dotenv::process(__DIR__); $dotenv->load(); ``` If already .env file existing on current directory without throwing error ``` $dotenv = Dotenv::process(__DIR__); $dotenv->safeLoad(); ``` If already .env file existing on current directory ``` $dotenv = Dotenv::process(__DIR__, 'myconfig.env'); $dotenv->load(); ``` Loads multiple `.env` files. ``` $dotenv = Dotenv::process(__DIR__, ['.env.local', '.env.example', '.env'], false); $dotenv->load(); ``` All of the defined variables are now available in the `$_ENV` and `$_SERVER` super-globals. ``` $s3_bucket = $_ENV['S3_BUCKET']; $s3_bucket = $_SERVER['S3_BUCKET']; ``` Nesting Variables ----------------- [](#nesting-variables) It's possible to nest an environment variable within another, useful to cut down on repetition. This is done by wrapping an existing environment variable in `${…}` e.g. ``` BASE_DIR="/var/webroot/project-root" CACHE_DIR="${BASE_DIR}/cache" TMP_DIR="${BASE_DIR}/tmp" ``` Requiring Variables to be Set ----------------------------- [](#requiring-variables-to-be-set) PHP dotenv has built in validation functionality, including for enforcing the presence of an environment variable. This is particularly useful to let people know any explicit required variables that your app will not work without. You can use a single string: ``` $dotenv->required('DATABASE_DSN'); ``` Or an array of strings: ``` $dotenv->required(['DB_HOST', 'DB_NAME', 'DB_USER', 'DB_PASS']); ``` Security -------- [](#security) If you discover a security vulnerability within this package, please send an email to All security vulnerabilities will be promptly addressed.
