How to get permission ?

I have create a simple facebook application. Now I want to get permission for read_stream.

I have read a lot of documentation but I don't understand.

Could you tell me how to get this permission with PHP or javascript ?

Edit:

I have used this source code ( you can se it working here ) but doesn't work because I get only basic permission:

<?php

require_once('facebook.php');

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => 'xxx',
  'secret' => 'xxx',
  'cookie' => true,
));


$session = $facebook->getSession();

$me = null;
// Session based API call.
if ($session) {
  try {
    $uid = $facebook->getUser();
    $me = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}

// login or logout url will be needed depending on current user state.

if (!$me) {
 $loginUrl = $facebook->getLoginUrl();


} else {

  // $fbme is valid i.e. user can access our app
  $logoutUrl = $facebook->getLogoutUrl();
}   


// This call will always work since we are fetching public data.
