database error using virtual hosts

I check for production and testing server, and default to development. Then that won't matter, and it's also useful if you have multiple developers.

Code:

switch($env)
{
  case 'www.domain.com':
    define('ENVIRONMENT', 'production');
    break;
  case 'dev.domain.com':
    define('ENVIRONMENT', 'testing');
    break;
  default:
    define('ENVIRONMENT', 'development');
    break;
}
