PHP querying whois database

Question

i am connecting to tld specific whois databases for whois information. Some just return:

Domain: domain.de
Status: connect

.com works fine for example How can i still get the full whois information?

my code:

$lookup = "";
    if(strlen($whois) > 0) {
        $fp = fsockopen($whois, 43, $errno, $errstr);
    } else {
        $fp = fsockopen(trim($server->server), 43, $errno, $errstr);
    }

    if (!$fp) {
        echo "ERROR: $errno - $errstr<br />\n";
    }
    fwrite($fp, "".$domain."\r\n");
    while (!feof($fp)) {
        $lookup .= fgets($fp);
    }
    fclose($fp);

You do realize that most people who feed WHOIS data have active countermeasures to stop you from doing this very thing, right? — Machavity, Dec 04 '14 at 14:30
why? it should be legit for everyone to check freely available whois data — pila, Dec 04 '14 at 14:32

Many country-specific registries will not give you full WHOIS records via port 43 queries. Some may give you nothing at all. You _have_ to go to their websites instead (and often enter captcha codes). Each one operates slightly differently. — Alex Riley, Dec 04 '14 at 18:27

.de operates at whois.denic.de. By default, while connecting to whois.denic.de on 43 they don't disclosure privacy information about domain owner. Terms and conditions says:

% The DENIC whois service on port 43 never discloses any information concerning
% the domain holder/administrative contact. Information concerning the domain
% holder/administrative contact can be obtained through use of our web-based
% whois service available at the DENIC website:
