在 php 中检索 Facebook 帖子的喜欢

Question

我正在寻找一种方法来根据其 post_id 检索 Facebook 帖子的点赞数。我从这个论坛本身获得了一个 php 代码。它有点像

 <?php
    function fetchUrl($url){
       return file_get_contents($url);
   }        

    $json_object = fetchUrl("https://graph.facebook.com/{post_id}/likes?access_token={token}&limit=5000000"); // 
    $feedarray   = json_decode($json_object, true);
    $likesNum = count($feedarray['data']); // return the number of items in `data` array

    print $likesNum;
?>

但问题是此方法无法检索帖子的总点赞数，因为点赞数以 1000 个为单位显示，然后会有另一个链接指向包含下一组 1000 个点赞数的不同页面，依此类推。

p>

有没有一种方法可以通过单个查询获得 Facebook 帖子的总点赞数？

添加摘要标志** summary=true**

“https://graph.facebook.com/{post_id}/likes?access_token={token}&summary=true”
