我想使用foreach循环从这个json响应中提取视频标题，缩略图，描述
我试过这个，但它给了我一个错误，请帮我解决这个问题。
我的PHP代码是
$link = 'https://www.googleapis.com/youtube/v3/search?order=rating&part=snippet&q=cars&maxResults=10&key={KEY}';
$video = file_get_contents($link);
$video = json_decode($video, true);
echo '<pre>';
print_r("query results:");
print_r($video);
'</pre>';
foreach ($video->items as $data ){
echo "{$data->snippet->title}";
echo "<br>";
}
