  $ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);

  if($ip){

  array_unshift($ips, $ip); $ip = FALSE;

  }

  for($i = 0; $i < count($ips); $i++){

  if (!eregi ("^(10|172\.16|192\.168)\.", $ips[$i])){

  $ip = $ips[$i];

  break;

  }

  }

  }

  return($ip ? $ip : $_SERVER['REMOTE_ADDR']);

  }

  echo get_real_ip();

  ?>

  方法六:

  if(getenv('HTTP_CLIENT_IP')){

  $onlineip = getenv('HTTP_CLIENT_IP');

  elseif(getenv('HTTP_X_FORWARDED_FOR')){

  $onlineip = getenv('HTTP_X_FORWARDED_FOR');

  }

  elseif(getenv('REMOTE_ADDR')){

  $onlineip = getenv('REMOTE_ADDR');
