如何读取方法的结果:listSubscriptions from Youtube PHP API

Question

在这种方法之后，我得到了这种格式的对象波纹管。谁能帮我如何从这个对象中读取标题和频道 ID？

$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"

这行得通吗？

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