PHP display server IP Address

I'm working on a website, and one of the things I would like to do is display MY IP address to users. The website is made with CodeIgniter, so I was looking to find my server IP with PHP. The IP address may change (it's a roamer), so I'd like to find it dynamically, not just hard code it. I tried this:

$data['hostname'] = NULL;
$data['ip'] = NULL;
$var = gethostname();
if ($var === FALSE) {
  $var = NULL;
} else {
  $data['hostname'] = $var;
  $data['ip']   = gethostbyname($var);
}

However, instead of giving me the Hostname and the IP, I got: "Moria" and "127.0.1.1". Not quite what I am looking for. Rather, it should say "Moria.student.rit.edu" for the Hostname, and the IP address. Any help?

If your laravel application is running on an internal server, you can use the following to get the external address of the server:

 $external_ip = exec('curl http://ipecho.net/plain; echo');

Try $_SERVER['SERVER_ADDR']. It will be the IP address that the server is listening on. You can use DNS functions (e.g., gethostbyaddr()) to get the host name.

See http://www.php.net/manual/en/reserved.variables.server.php.
