You can get the Email Address, directly without using the FQL.

// initialize facebook
 $facebook = new Facebook(array(
        'appId' => APP_ID,
        'secret' => APP_SECRET));

 $session = $facebook->getSession();
 if ($session) {
 try {
    $fbme = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}
else
{
  echo "You are NOT Logged in";
}

//getting the login page if not signned in
if (!$fbme) {
  $loginUrl = $facebook->getLoginUrl(array('canvas' => 1,
                                      'fbconnect' => 0,
                                      'req_perms' =>                   'email,user_birthday,publish_stream',
                                      'next' => CANVAS_PAGE,
                                      'cancel_url' => CANVAS_PAGE ));
 echo '<fb:redirect url="' . $loginUrl . '" />';
 } else {

      // $fbme is valid i.e. user can access our app
     echo "You can use this App";
 }

 // getting the profile data
 $user_id = $fbme[id];
 $name=$fbme['name'];
 $first_name=$fbme['first_name'];
 $last_name=$fbme['last_name'];
 $facebook_url=$fbme['link'];
 $location=$fbme['location']['name'];
 $bio_info=$fbme['bio'];
 $work_array=$fbme['work'];
 $education_array=$fbme["education"];
 $email=$fbme['email'];
 $date_of_birth=$fbme['birthday'];

This code worked for me..and i go all the information needed with the Email ID.

NOTE: User has to allow us to get their Information during the Approval of Application.
