如何在youtube评论中显示回复。
这是代码
$videoid = 'UKdZU9Db6fk';
$apikey = 'API KEY';
$json = file_get_contents('https://www.googleapis.com/youtube/v3/commentThreads?maxResults=100&part=snippet%2Creplies&videoId='.$videoid.'&key='.$apikey);
$ytdata = json_decode($json);
foreach ($ytdata->items as $item) {
echo "Author: ". $item->snippet->topLevelComment->snippet->authorDisplayName;
echo "Comment: ". $item->snippet->topLevelComment->snippet->textDisplay;
foreach ($ytdata->items->replies as $iteminner) {
echo "Reply: ". $iteminner->comments[0]->textDisplay;
}
}
它显示评论，但是对特定评论的回复是我不能做的，如果有评论有自己的回复，那该怎么办。
我一直在网上搜索，大多数问题都是一样的，他们也有同样的问题。
我正在尝试将foreach添加到foreach中，但结果是
"Trying to get property of non-object" "Invalid argument supplied for foreach() "
以下是xml数据的方法

答案 0 :(得分：0)
谢谢@CBroe
这部分代码工作正常
foreach ($ytdata->items as $item) {
echo "Author: ". $item->snippet->topLevelComment->snippet->authorDisplayName;
echo "Comment: ". $item->snippet->topLevelComment->snippet->textDisplay;
}
但是当我在foreach中添加foreach时，我得到的是错误结果
