如何检查当前的Facebook用户是否喜欢使用PHP SDK的页面？

Question

如何检查当前的Facebook用户是否像Facebook页面一样？

我有这个代码,

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'
      ));
    }

但如果用户喜欢该页面,则无法回复,请参阅此处的页面

谢谢!

您可以使用FQL

$isFan = $facebook->api(array(
  "method" => "fql.query",
  "query"  => "SELECT uid FROM page_fan WHERE page_id = '<YOUR PAGE ID>' AND uid = '<UID>"
));
