SRV record lookup with PHP

Question

If you type

nslookup -type=SRV _xmpp-server._tcp.gmail.com

(or use the dig command in OSX) you get some SRV records relating to google chat

Answer 1

You could use Pear Net_DNS. I managed to get this to work on Linux, but haven't tested it on Windows or any others:

require_once('Net/DNS.php');
$resolver = new Net_DNS_Resolver();
$response = $resolver->query('_xmpp-server._tcp.gmail.com', 'SRV');
if ($response) {
    foreach ($response->answer as $rr) {
        $rr->display();
    }
}

I modified the example from their documentation. hope this helps
