Use PHP to query domain name status whois class_PHP tutorial

Copy code The code is as follows:

class SearchDomain
{
var $domain="";
function SetDomain($udomain)
{
$this->domain = $udomain;
}
//
// Get whois and analyze domain name status
// ok Not registered
// Non-null value Expiration time
// Null value Unknown
//
function GetInfo()
{
/*
$dinfo = trim($this->GetWhois());
if($dinfo==" ") return "";
if(eregi("no match",$dinfo)) return "ok";
//return $rs;
*/
$wl = "";
$w_server = $this->GetServer();
if($w_server=="") return "";
$fp = fsockopen($w_server, 43, $errno, $errstr, 30);
if(!$fp)
{
echo $errstr;
return "";
}
$out = $this->domain."rn" ;
$out .= "Connection: Closernrn";
fputs($fp, $out);
while (!feof($fp))
{
$wl = fgets( $fp, 255);
if(eregi("no match",$wl))
{
fclose($fp);
return "ok";
}
if(eregi("Expiration Date",$wl))
{

}
