在 PHP 中使用 Youtube API V3 检索缩略图和视频时间

Question

我跟着这个啧啧 https://packagist.org/packages/alaouy/youtube

一切顺利，但我在这段代码中遇到了问题：

$video = Youtube::getVideoInfo('rie-hPVJ7Sw');
var_dump($video);

这是我得到的回复：

抱歉输出行太长了。

我要的是视频时长、缩略图和视频标题。

我想它应该是这样的形式。

<?php
  foreach($item as $video)
   {
    echo $item['snippet']['thumbnails]['default'];
   }
?>

类似的东西不断抛出错误。

这是一个标准类，不是数组。获取信息的正确方法是

<?php
    $video = Youtube::getVideoInfo('rie-hPVJ7Sw');
    echo $video->snippet->thumbnails->default->url;
?>
