如何从图形API中调用一个项目？ [英] How to call an item from graph api fb?

问题描述

我想从请求的api调用中选择一个特定的field.item并回显它。例如：

I want to select an specific field.item from the requested api call and echo it.for example something like this:

$getlike = $facebook->api("/fql?q=SELECT%20like_info%20FROM%20stream%20WHERE%20post_id=".$id);

$getcm = $getlike['data']['like_info']['user_likes'];
echo $getcm;

上述代码的JSON：

{
  "data": [
    {
      "like_info": {
        "can_like": true, 
        "like_count": 70, 
        "user_likes": false
      }
    }
  ]
}

当我回调$ getcm时，它不会返回任何东西。有什么问题吗？

When i echo the $getcm,it wont return anything.Is there anything wrong?

推荐答案

数据是一个数组;所以你应该把它取出来像 -

data is an array; so you should fetch it like-

$getcm = $getlike['data'][0]['like_info']['user_likes'];
echo $getcm;
