Facebook：在like和comment数组中为foreach（）提供的参数无效

Question

我正在尝试从facebook中检索。以下代码检索所有ID。但是我收到错误为foreach（）提供的无效参数为行 foreach（$ status ['喜欢''['data']为$ likesData）

$statuses = $facebook->api('/me/statuses');

foreach($statuses['data'] as $status){

   foreach($status['likes']['data'] as $likesData){

   $frid=$likesData['id']; 
   echo  $frid;
   echo  "<br>";
   }
   }

Answer 1

并非所有状态都喜欢（就像并非所有状态都有评论一样）所以您需要首先检查状态是否喜欢：

$statuses = $facebook->api('/me/statuses');
foreach($statuses['data'] as $status){
    if(!empty($status['likes'])) {
        foreach($status['likes']['data'] as $likesData){
            $frid=$likesData['id']; 
            echo  $frid;
            echo  "<br>";
        }
    }
}

显然你需要先检查一下你是否有任何状态！
