Access of env-vars in Constants.php

Thank you.

Is there an alternative what i can do instead in order to keep these constants? Do i have to create something different and change the constants? (helper, files in Config/Boot Directory). It was nice if you can give me an idea, thanks.

I have a appConstants.php file which is "required" at the end of Constants.php and looks something like this:-

Code:

switch ($_SERVER['SERVER_NAME']) {
  case '127.0.0.1':
  case 'localhost':
    define('ENVIRONMENT', 'development');
    define('LOCALHOST', true);
    define('DB_SETTINGS', 'D:/......../dev-db.php');
    define('WEB_HOMEPAGE', 'http://' . $_SERVER['SERVER_NAME']);
    break;
  case '.......test.co.uk':
    define('ENVIRONMENT', 'test');
    define('LOCALHOST', false);
    define('DB_SETTINGS', '/home/......./secure/test-db.php');
    define('WEB_HOMEPAGE', 'https://' . $_SERVER['SERVER_NAME']);
    break;
  case '..........co.uk':
  case 'www............co.uk':
    define('ENVIRONMENT', 'production');
    define('LOCALHOST', false);
    define('DB_SETTINGS', '/home/......../secure/prod-db.php');
    define('WEB_HOMEPAGE', 'https://' . $_SERVER['SERVER_NAME']);
    break;
  default:
    die('Unknown ENVIRONMENT: ' . $_SERVER['SERVER_NAME']);
    break;
}
