.env.laravel

Upon each HTTP request or command-line interaction, Laravel’s foundation boots up. The framework uses the Dotenv library (by Vance Lucas) to parse the .env file. The \Dotenv\Dotenv class loads the file, parses each line, and populates the $_ENV and $_SERVER superglobals. Laravel’s helper functions—most notably env() —provide a convenient way to retrieve these values throughout the application.
