我想对某些YouTube视频的回复发表评论。我在PHP中使用youtube数据API，任何人都可以为我提供评论的PHP代码???
以下是此API的完整文档，也有关于评论，但提供的代码无效
$newComment = $yt->newCommentEntry();
$newComment->content = $yt->newContent()->setText('new comment');
// post the comment to the comments feed URL for the video
$commentFeedPostUrl = $videoEntry->getVideoCommentFeedUrl();
$updatedVideoEntry = $yt->insertEntry($newComment, $commentFeedPostUrl,
'Zend_Gdata_YouTube_CommentEntry');
我没有得到如何使用vedioEntry对象。 cz没有关于此对象的文档演示。任何人都可以告诉它如何运作.............
的错误
