    }
}
?>

调用

include './class.php';
$target = isset($_GET['ip'])?gethostbyname($_GET['ip']):'NULL';
if('NULL' == $target || '' == $target)$result = '

Please Input An IP Address

';
else
{
    $whois = new IPWhois($target);
    //$result = "IP Whois Information For ".$_POST['ip']."

";
    $result = $whois->ShowInfo();
}
echo $result;
?>
