我编写了以下代码来了解 fql 多查询是如何工作的：

include_once "fbmain.php";
try{     
$your_id=xxxxxxxx;
     $fql= '{
     "friends":"SELECT uid2 FROM friend WHERE uid1='.$your_uid.',"
     "friendinfo":"SELECT * FROM standard_user_info WHERE uid IN (SELECT uid2
                  FROM #friends)"
             }';
$res = $facebook->api_client->fql_multiquery($fql);   
   }
catch(Exception $o){
        d($o); // d() is function to print
    }

但输出显示错误

在第 9 行调用非对象上的成员函数 fql_multiquery()

我也尝试过其他查询而不是这两个，但问题仍然存在。我正在使用 php sdk 3.0。

请帮忙。

我不使用多查询，因为 fql 已移至图形 api。相反，我使用批处理请求。这是 /feed 请求的示例，第 10 个结果的评论和第 10 个帖子的永久链接的 fql multi。我相信这对于您需要的东西来说有点过头了，但这是我混合图形和 fql 以及使用名称功能的最佳示例，这似乎是您携带朋友所需要的。

看起来相当有问题的实例化

$facebook->api_client

还值得注意的是，在 [standard_user_info] 列 [uid] 是字符串类型，因此您可能还需要添加引号。
https://developers.facebook.com/docs/reference/fql/standard_user_info/

根据 FB 文档，FQL 多查询应该比后续的批处理调用更快。 https://developers.facebook.com/docs/reference/fql/
