推荐答案

在电子邮件权限中使用facebook->getLoginUrl，请参阅

use facebook->getLoginUrl with Email Permissions, see https://developers.facebook.com/docs/reference/login/email-permissions/ (scope' => 'email')

facebook.php :

<?
error_reporting(E_ALL);
ini_set('display_errors','on');
require 'facebook-php-sdk-master/src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => <YOUR AppId>,
  'secret' => <YOUR APPsecret>,
));

$applicationurl = 'http://testdrive.nl/facebook.php';

// Get User ID
$user = $facebook->getUser();

if(empty($user))
{
    $params = array(
  'scope' => 'email',
  'redirect_uri' => $applicationurl
   );   

$loginUrl = $facebook->getLoginUrl($params);
header('Location: ' . $loginUrl ."\r\n");
exit;
}   

$fql = 'SELECT contact_email FROM user WHERE uid = '.$user;
$res = $facebook->api(array('method' => 'fql.query',
                            'query' => $fql));
//var_dump($res);
echo $res[0]['contact_email'];
