function checkDomain($domain,$server,$findText){
// Open a socket connection to the whois server
$con = fsockopen($server, 43);
if (!$con) return false;

// Send the requested doman name
fputs($con, $domain."\r\n");

// Read and store the server response
$response = ' :';
while(!feof($con)) {
$response .= fgets($con,128);
}

// Close the connection
fclose($con);

// Check the response stream whether the domain is available
if (strpos($response, $findText)){
return true;
}

}

function showDomainResult($domain,$server,$findText){
if (checkDomain($domain,$server,$findText)){
