Get YouTube video thumbnail and use it with PHP
提问by Ron
How can I access thumbnail collection of a YouTube video using the link of the video from the YouTube API.
I want thumbnails to be displayed on website using PHP using the video id stored in a variable for example $link
如何使用来自 YouTube API 的视频链接访问 YouTube 视频的缩略图集合。例如，我希望使用存储在变量中的视频 ID 使用 PHP 在网站上显示缩略图$link
回答by Ron
YouTube stores many different types of thumbnails on its server for different devices. You can access it by using the video id which
every YouTube video has. You can display the images on your website using a variable $linkwhich holds the id of the video and substituting it
in the place for video_ID in the link.
YouTube 在其服务器上为不同设备存储了许多不同类型的缩略图。您可以使用每个 YouTube 视频都有的视频 ID 来访问它。您可以使用$link保存视频 ID 的变量在您的网站上显示图像，并将其替换为链接中 video_ID 的位置。
Low quality thumbnail:
低质量缩略图：
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/sddefault.jpg
Medium quality thumbnail:
中等质量缩略图：
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/mqdefault.jpg
High quality thumbnail:
高质量缩略图：
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/hqdefault.jpg
Maximum quality thumbnail:
最高质量缩略图：
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/maxresdefault.jpg
Example:
例子：
If you want to access the thumbnail of the following video:
如果您想访问以下视频的缩略图：
https://www.youtube.com/watch?v=Q-GYwhqDo6o
Video ID : Q-GYwhqDo6o
视频编号： Q-GYwhqDo6o
So, this is how video thumbnail link looks like:
所以，这就是视频缩略图链接的样子：
http://img.youtube.com/vi/Q-GYwhqDo6o/mqdefault.jpg
Hope it helps. Enjoy coding.
希望能帮助到你。享受编码。

To get high-quality image you can use the following URL which is fetched from youtube API
要获得高质量的图像，您可以使用从 youtube API 获取的以下 URL
$video_id = explode("?v=", $link);
$video_id = $video_id[1];
$thumbnail="http://img.youtube.com/vi/".$video_id."/maxresdefault.jpg";

您可以使用以下代码。这对我来说是工作。根据您的要求选择图像质量。
<?php
$youtubeID = getYouTubeVideoId('youtube video url');
$thumbURL = 'https://img.youtube.com/vi/' . $youtubeID . '/mqdefault.jpg';
print_r($thumbURL);
function getYouTubeVideoId($pageVideUrl) {
$link = $pageVideUrl;
$video_id = explode("?v=", $link);
if (!isset($video_id[1])) {
$video_id = explode("youtu.be/", $link);
}
$youtubeID = $video_id[1];
if (empty($video_id[1])) $video_id = explode("/v/", $link);
$video_id = explode("&", $video_id[1]);
$youtubeVideoID = $video_id[0];
if ($youtubeVideoID) {
return $youtubeVideoID;
} else {
return false;
}
}
?>
