$url = "https://graph.facebook.com/fql?q=" . urlencode($query) . 
     "&access_token=" . $access_token;
$data = json_decode( file_get_contents ($url));
$boys = count($data[data]);

我已经尝试过这种方法，但无法得到想要的结果......我想做一个这样的应用程序

Answer 1

不幸的是，FQL 不支持COUNT()你需要的 SQL 函数，这里。

您必须检索朋友的性别列表并遍历它们。

在 FQL 中：SELECT sex FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me())

图 API：https://graph.facebook.com/me/friends?fields=gender
