基本上,我想列出YouTube频道的最新上传内容,但是我在使用for循环时遇到了麻烦,或者我也错过了foreach的使用.
我尝试了以下方法:
function last_uploads() {
for($i = 0; $i < 20; ){
error_reporting(E_ALL);
$url = 'https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=UCBR8-60-B28hp2BmDPdntcQ&maxResults=3&key={key}&type=video';
$json = file_get_contents($url);
$json_data = json_decode($json, false);
$id = $json_data->items[0]->id->videoId;
echo '<iframe id="ytplayer" type="text/html" width="auto" height="auto"
src="http://www.youtube.com/embed/' . $id . '?rel=0&showinfo=1"
frameborder="0" allowfullscreen></iframe><br class="clear" />';
}
$i++;
break;
}
供稿网址($url)的输出如下:

问题是last_uploads()返回最后1个视频,并一直重复播放直到出现120秒以上的错误.
有什么想法吗?
问候,
谢谢!
解决方法:
搞砸了
>您的for循环将无限期执行直到超时,因为$i在for循环之后. (事实是,甚至不需要for循环,因为您正在从频道中获取最新的3个视频-无需重复20次).
>您的代码仅获取返回的第一个视频的ID.这是for循环遍历结果的地方.
foreach($json_data-> items as $item){
$id = $item-> id-> videoId;
#打印你的东西
}
