would probly work better this way

PHP Code:

function getip() {
  $check = array('HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED',
                 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED',
                 'HTTP_VIA', 'HTTP_X_COMING_FROM', 'HTTP_COMING_FROM');

  foreach ($check as $c) {
    if (isset($_SERVER[$c]) AND ip_valid($_SERVER[$c])) {
      return ip_first($_SERVER[$c]);
    }
  }

  return $_SERVER['REMOTE_ADDR'];
}
