Well, you should post what you have got so far..anyway, as described in the documentation:

The data is passed to your application as a signed request. The signed_request parameter is a simple way to make sure that the data you're receiving is the actual data sent by Facebook.

So you need to specify the redirect_uri and then process/extract the data you want from the signed_request and email it with the method you are using. How to process the data is described in the bottom of the document I linked above: 

<?php
define('FACEBOOK_APP_ID', 'your_app_id');
define('FACEBOOK_SECRET', 'your_app_secret');

function parse_signed_request($signed_request, $secret) {
  list($encoded_sig, $payload) = explode('.', $signed_request, 2); 

  // decode the data
  $sig = base64_url_decode($encoded_sig);
  $data = json_decode(base64_url_decode($payload), true);

  if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') {
    error_log('Unknown algorithm. Expected HMAC-SHA256');
    return null;
  }

  // check sig
  $expected_sig = hash_hmac('sha256', $payload, $secret, $raw = true);
  if ($sig !== $expected_sig) {
    error_log('Bad Signed JSON signature!');
    return null;
  }

  return $data;
}

function base64_url_decode($input) {
    return base64_decode(strtr($input, '-_', '+/'));
}

if ($_REQUEST) {
  echo '<p>signed_request contents:</p>';
  $response = parse_signed_request($_REQUEST['signed_request'], 
                                   FACEBOOK_SECRET);
  echo '<pre>';
  print_r($response);
  echo '</pre>';
} else {
  echo '$_REQUEST is empty';
}
?>

So instead of the print_r and echo functions, send the fields you want!
