Here is a very simple Whois script in PHP. You can try this.
Thank you.
<?
$server="whois.networksolutions.com";//try any whois servers
if ($domaim)
{
$fp = fsockopen($server, 43, &$errno, &$errstr, 30);
fputs($fp, $domaim);
$data = fread( $fp, 100000);
?>
<textarea wrap=off name=whoisinfo cols=75 rows=20><?echo$data;?></textarea>
<?
}
else
{
?>
<form name="whois" method="get">
Domain : <input class=field type="text" name="domaim" size="40"><input type="submit" value=" Go ">
</form>
<?
}
?>
