你應該能夠做到這一點與一個班輪：

$total = $response->results->sum('trackTimeMillis');

我想爲其他15個數組獲得trackTimerMilis以及 –

'sum'方法將爲集合中的每個項目添加「trackTimerMillis」值。看一看'Illuminate \ Support \ Collection'的'sum'方法 - https://laravel.com/docs/5.4/collections#method-sum – Desh901

哦，你想總結和檢索它們中的每一個？ – Desh901

這是一個簡單的可迭代對象，沒有什麼特別的或Laravel相關的。

你可以這樣做：

$sum = 0; 

foreach ($response['results']->items as $item) { 
    $sum += $item->trackTimeMillis; 
} 

var_dump($sum);

不能使用類型爲stdClass的對象作爲數組 –

對不起，我看錯了採集。用更新後的代碼重試。 – GiamPy
