Hi Everyone,
I was wondering can someone with Ajax experience to have a look at the following PHP script. Its a simple domain checker.
I am using sessions to pass data from page to page but when I get to this domain checker page and I search for a domain it clears the session.
I was thinking if this form was in ajax it would solve my problem. Unfortunately I know nothing of Ajax and I was wondering would someone be so kind to have a look at it for me?
I hope you can help,
Kind Regards,
Paul
<?php
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, $findText)){
return true;
}
else {
return false;
}
}
function showDomainResult($domain,$server,$findText){
if (checkDomain($domain,$server,$findText)){
echo "<tr><td>$domain</td><td>AVAILABLE</td></tr>";
