Laravel - accessing .env variables

Route::get('/test', function () {
    return "it is".config('app.name');
});

With Laravel, you should avoid environmental variables outside of your configuration files.

In your config files, you can use environmental variables, example in config/app.php:

'env' => env('APP_ENV', 'production'),

Then you can access this using the config helper: config('app.env').

This allows you to cache your configuration and still access these values, since env('APP_ENV') will no longer work once your config is cached.
