Check if a user likes my page via website

如何检查通过facebook php sdk登录到我的网站的用户是否喜欢我的页面，以便我可以向他展示一些秘密内容…

如果你有适当的权限，你可以访问用户的Likes属性:然后你可以检查返回的列表，看看你的URL是否在列表中。你可以这样写:

$likes = Facebook::api('/me/likes','GET');

这里是另一种使用check if $signed_request->page->liked:

的方法

function parsePageSignedRequest() {
    if (isset($_REQUEST['signed_request'])) {
      $encoded_sig = null;
      $payload = null;
      list($encoded_sig, $payload) = explode('.', $_REQUEST['signed_request'], 2);
      $sig = base64_decode(strtr($encoded_sig, '-_', '+/'));
      $data = json_decode(base64_decode(strtr($payload, '-_', '+/'), true));
      return $data;
    }
    return false;
  }
  if($signed_request = parsePageSignedRequest()) {
    if($signed_request->page->liked) {
      echo "This content is for Fans only!";
    } else {
      echo "Please click on the Like button to view this tab!";
    }
  }
