class IPWhois
{
var $server = 'whois.arin.net';
var $target;
var $timeout = 10;
var $msg;
function IPWhois($target)
{
$this->target = $target;
}
function ShowInfo()
{
if($this->_CheckIP($this->target))
{
$this->msg = $this->_GetInfo($this->server);
if($this->_CheckInfo($this->msg))
{
$this->msg = $this->_GetInfo($this->server);
}
}
else $this->msg = '<p>Please Enter An IP Address<br></p>';
return $this->msg;
}
function _CheckIP($temptarget)
{

{
$f = 1;
$detail = explode(".",$temptarget);
foreach($detail as $v)
{
if($v > 255 $v < 0)
{
$f = 0;
break;
}
}
}
else $f =0;
return $f;
}
function _GetInfo($tempserver)
{
$this->msg = '';
if(!$sock = fsockopen($tempserver, 43, $num, $error, $this->timeout))
{
unset($sock);
$this->msg = "Timed-out connecting to $tempserver (port 43)";
}
else
{

$this->msg .= "-----------------------------------------------------------------<BR>";
while (!feof($sock))

$this->msg .= "-----------------------------------------------------------------<BR></p>";
}
fclose($sock);
return nl2br($this->msg);
}
function _CheckInfo($tempmsg)
{
if(eregi("whois.ripe.net", $tempmsg))
{

elseif(eregi("whois.lacnic.net", $tempmsg))
{
$this->server = "whois.lacnic.net";
return 1;
}
else return 0;
}
}
?>
调用
<?php
include './class.php';
$target = isset($_GET['ip'])?gethostbyname($_GET['ip']):'NULL';
if('NULL' == $target '' == $target)$result = '<p>Please Input An IP Address<br></p>';
else
{
$whois = new IPWhois($target);
//$result = "IP Whois Information For <b>".$_POST['ip']."</b><br><br>";
$result = $whois->ShowInfo();
}
echo $result;
?>
