Help with a little problem in a script

I have a a script that search whois and give respond if a domain is free or not. The problem is that im only able to search one domain a time,

Works
digitalpoint.com

Not working
digitalpont.com
digitalpoint.com


How do i do to make is search several domains?

 

Use a loop.

 

I did try but couldnt find how to input it in right way. Maybe you could help me with it? Its a really short code so should be easy for some one who knows.

 

Post it here and I'll take a look.

 

There you have it.

<?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,$findText)){
echo "<div>$domain - Available</div>";
}
else echo "<div>$domain - Taken</div>";
}
?>

<?php

$domainbase = (isset($_POST['domainname'])) ? $_POST['domainname'] : '';
$d_all = (isset($_POST['all'])) ? 'all' : '';
$d_com = (isset($_POST['com'])) ? 'com' : '';
$d_net = (isset($_POST['net'])) ? 'net' : '';
$d_org = (isset($_POST['org'])) ? 'org' : '';

// Check domains only if the base name is big enough
if (strlen($domainbase)>0){
?>
<br />
<strong>Searched domains</strong>
<div id="result">
<?php
