check domain name availability

Hi guys,

is there anyone can give me an idea how to write a simple code to check the availability of a domain name... last time one of my friend told me that i can use socket function to check and he did give me the sample code.. unfortunately, i lost the code..

can u guys assist me on this ? please advise.

thanks

Hi

You need a function to query a DNS Server using sockets.

Try something like this


<?
function whois($name)
{
$soc = fsockopen('whois.geektools.com', 43);
if($soc)
{
fputs($soc, $name.'\r\n');
while(!feof($soc))
{
$info .= fread($soc, 1024);
}
fclose($soc);
}
return $info;
}

echo whois($_POST['search']);
?>

It would make life simpler to use create an instance of this domain class: http://aspn.activestate.com/ASPN/Co...P/Recipe/266624
