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

I would like to replicate this functionality in PHP, does anyone have any good ideas how to do this?

I would like to avoid using exec() as this does not return 100% standard responses across OSX/*NIX/WINDOWS

Thanks!

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
