如何閱讀方法的結果：從Youtube PHP API

Question

listSubscriptions這個方法我已經得到了對象波紋管的這種格式後。任何人都可以幫助我如何從這個對象讀取標題和channelId？

$subscriptionResponse = $youtube->subscriptions->listSubscriptions('snippet', 
    array('channelId' => 'MY_CHANEL_ID', 'maxResults' => '50')); 

echo "<pre>"; 
     print_r($subscriptionResponse['items']); 
echo "</pre>"; 
        die();  

Array 
(
    [0] => Google_Service_YouTube_Subscription Object 
     (
      [contentDetailsType:protected] => Google_Service_YouTube_SubscriptionContentDetails 
      [contentDetailsDataType:protected] => 
      [etag] => "xxxxxxxxxxxxxxxxx" 
      [id] => xxxxxxxxxxxxxxxxx

Answer 1

這是行得通的嗎？

foreach ($subscriptionResponse['items'] as $item) { 
echo $item['data']['snippet']['title']; 
echo $item['data']['snippet']['channelId']; 
}
