  • APP_ENV: This may determine how various services behave in your application
  • APP_KEY: This key is used by the application for encryption and should be set to a random, 32 character string, otherwise these encrypted strings will not be safe. Use 'php artisan key:generate' to generate a new key. Please do this before deploying an application!
