When I try to lookup the domain registrar detail I received the error "Socket Error ******* - Unable to find the socket transport "http"- did you forget to enable it when you configured PHP?"
public function whoislookup($domain){
$domain = trim($domain); //remove space from start and end of domain
if(substr(strtolower($domain), 0, 7) == "http://") $domain = substr($domain, 7); // remove http:// if included
if(substr(strtolower($domain), 0, 4) == "www.") $domain = substr($domain, 4);//remove www from domain
if(preg_match("/^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/",$domain))
return $this->queryWhois("whois.lacnic.net",$domain);
elseif(preg_match("/^([-a-z0-9]{2,100})\.([a-z\.]{2,8})$/i",$domain))
{
$domain_parts = explode(".", $domain);
$tld = strtolower(array_pop($domain_parts));
$server = $this->WHOIS_SERVERS[$tld][0];
if(!$server) {
return "Error: No appropriate Whois server found for $domain domain!";
}
$res=$this->queryWhois($server,$domain);
while(preg_match_all("/Whois Server: (.*)/", $res, $matches))
{
$server=array_pop($matches[1]);
$res=$this->queryWhois($server,$domain);
}
return $res;
}
else
return "Invalid Input";}
private function queryWhois($server,$domain)
{
$fp = @fsockopen($server, 43, $errno, $errstr, 20) or die("Socket Error " . $errno . " - " . $errstr);
if($server=="whois.verisign-grs.com")
$domain="=".$domain;
fputs($fp, $domain . "
");
$out = "";
while(!feof($fp)){
$out .= fgets($fp);
}
fclose($fp);
return $out;
}
I am getting the domain name from the different function. Use that domain name in this function and search the whois database for getting the information of the domain registration.
