php 印出 json array一直失敗?

Question

{ "list": [ { "attribute-id": "f11", "name": "love", "type": "me" }, { "attribute-id": "f12", "name": "member", "type": "her" }, { "attribute-id": "f13", "name": "user", "type": "her" }, { "attribute-id": "f14", "name": "like", "type": "me" } ] } 我利用curl跟別人的後端api撈過來以上的數據對方的需求是要告知type $data = array( "type" => "skill" ); $data_string = json_encode($data); $result = curl_exec($ch); 於是我印出 echo $result，取得的結果是同一個type沒錯 但我想在我這端用php印出來例如所有的名字 foreach($result->list as $mydata) { echo $mydata->name; } 但這樣卻沒辦法印出Notice: Trying to get property 'list' of non-objectWarning: Invalid argument supplied for foreach() 是哪裡有問題？！

需要先将$result结果使用$result = json_decode($result, true);解析为数组，之后再执行如下操作

foreach($result['list'] as $mydata)
{
    echo $mydata['name'];
}
