如何检查当前的Facebook用户是否喜欢Facebook页面?

How can i check if the current facebook user like a facebook page?

我有此代码

require_once("/path/to/sdk/facebook.php");


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

    $user = $facebook->getUser();

    if ($user) {
      try {
        $likes = $facebook->api("/me/likes/153649677989200");
        if( !empty($likes['data']) )
            echo "I like!";
        else
            echo "not a fan!";
      } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
      }
    }

    if ($user) {
      $logoutUrl = $facebook->getLogoutUrl();
    } else {
      $loginUrl = $facebook->getLoginUrl(array(
        'scope' => 'user_likes'
      ));
    }

但是如果用户喜欢该页面，则没有响应，请参阅页面

But is not responding if the user like the page, please see the page here

谢谢！
