How to test if a domain is available

[knickerlas]

Hi all

I was just looking for a kick in the right direction on the topic of domain name testing. Particularly .dk's

I'm not looking for detailed descriptions just a little direction to get me started.

Many thanks

Nick,

Most standard linux distributions come with whois. You can use php functions to execute whois and display output on the browser.

If you want to use it from command line just type whois <yourdomain.ext>.

There's something called php-whois I think you'll find it on SourceForge.com

It does what you want with a little tweaking.

if($domainname=="")
{
error("You must enter a domain name!");
$goback=1;
}
$validate=$domainname.$tld;
if(!ereg('^{[-!#$%&\'*+\/0-9=?A-Z_a-z{|}~]+\.'.'[-!#$%&\'*+\\./0-9=?A-Z^_a-z{|}~]+$',$validate))}
{
$goback=1;
error("Bad Domain Name!");
}

    if($tld==".co.uk" || $tld==".org.uk")
    {
            $whois="whois.nic.uk";
    }
    if($tld==".com" || $tld==".net" || $tld==".org")
    {
            $whois="rr-n1-tor.opensrs.net";
    }
    if($tld==".info")
    {
            $whois="whois.afilias.net";
    }
    if($goback==1)
    {
    }else{
    $info="";
    $fp = fsockopen ("$whois", 43, &$errnr, &$errstr) or die("$errno: $errstr");
    fputs($fp, "$domainname$tld\n");
    while (!feof($fp))
    $info.=fgets($fp, 2048);
    fclose($fp);
    $info=nl2br($info);

echo $info;

then do something like
if (strstr(strtoupper($info),strtoupper("No Match")) || strstr(strtolower($info),"not found")){
}else{

etc....

Thanks guys, the code is probably a little overkill for my needs but I'll work on the whois connection.
