json - 如何在 php 中读取 youtube 数据 api v3 响应

Question

我有以下代码:

$yt_profiles = $youtube->channels->listChannels('brandingSettings', array(
'mine' => 'true',
));

返回以下输出:

Google_Service_YouTube_ChannelListResponse Object

我想遍历 modelData:protected 变量以获取 channel 列表及其项目数据。它的 json 对象所以 $yt_profiles->modelData:protected 在访问时不起作用。请帮我解决这个问题。提前致谢

您可以像在数组中一样访问它:

print_r ($yt_profiles['modelData']);
