您可以从 youtube oembed 界面以两种格式获取数据：XML 和 JSON
接口地址：http ://www.youtube.com/oembed?url=youtubeurl&format=json
使用此 PHP 函数获取数据
function get_youtube($url){
$youtube = "http://www.youtube.com/oembed?url=". $url ."&format=json";
$curl = curl_init($youtube);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$return = curl_exec($curl);
curl_close($curl);
return json_decode($return, true);
}
$url = // youtube video url
// Display Data
print_r(get_youtube($url));
不要忘记extension=php_curl.dll 在您的php.ini

这将返回有关视频的元数据：
http://www.youtube.com/oembed?url={videoUrlHere}&format=json
使用您的示例，调用：
http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=B4CRkpBGQzU&format=json
返回以下内容，您可以使用 PHP 对其进行消化和解析：
{
"provider_url": "http:\/\/www.youtube.com\/",
"thumbnail_url": "http:\/\/i3.ytimg.com\/vi\/B4CRkpBGQzU\/hqdefault.jpg",
"title": "Joan Osborne - One Of Us",
"html": "\u003ciframe width=\"459\" height=\"344\" src=\"http:\/\/www.youtube.com\/embed\/B4CRkpBGQzU?fs=1\u0026feature=oembed\" frameborder=\"0\" allowfullscreen\u003e\u003c\/iframe\u003e",
"author_name": "jzsdhk",
"height": 344,
"thumbnail_width": 480,
"width": 459,
"version": "1.0",
"author_url": "http:\/\/www.youtube.com\/user\/jzsdhk",
"provider_name": "YouTube",
"type": "video",
"thumbnail_height": 360
}

另一个有用的 URL API 是：https ://www.youtube.com/get_video_info?video_id=B4CRkpBGQzU
video_id 是 YouTube 的“v”参数。结果是一个 URL 编码格式的字典 (key1=value1&key2=value2&...)
这是长期存在的无证 API，因此探索它取决于开发人员。我知道“状态”（正常/失败）、“错误代码”（在我的实践中为 100 和 150）、“原因”（错误的字符串描述）。我以这种方式获得持续时间（“length_seconds”），因为 oEmbed 不提供此信息（奇怪但真实），我几乎无法激励每个雇主从 YouTube 获取密钥以使用官方 API

要获取youtube视频description、不同大小thumbnail等tags，请使用更新的v3 googleapis
示例网址：https ://www.googleapis.com/youtube/v3/videos?part=snippet&id=7wtfhZwyrcc&key=my_google_api_key
$google_api_key = 'google_api_key';
$video_id = 'youtube_video_id';
$api_url = 'https://www.googleapis.com/youtube/v3/videos?part=snippet&id='.$video_id.'&key='.$google_api_key;
$json = file_get_contents($api_url);
$obj = json_decode($json);
var_dump($obj);

$video->video = "http://www.youtube.com/playlist?list=PL6F5E9FD99326F98C";
$youtube = $video->playVideo();
echo $youtube . "<hr>";
// 1 video
$video->video="http://www.youtube.com/watch?v=uTA5bLxfvwo";
$youtube = $video->playVideo();
echo $youtube;
// shared link
echo "<hr>";
$video = new YouTube(420,315);
$video->video="http://youtu.be/VRl2XFJ_tg4";
$youtube = $video->playVideo();
echo $youtube;
// invalid request
$video->video = "http://wrongvideo.com?nothere";
// Your own error message
$video->error ="<br>Video not found :-(<br>" ;
$youtube = $video->playVideo();
echo $youtube;
?>

我知道这是一个老问题，但我为此目的写了一个包，我会把它放在这里也许有人需要这个。
composer require smoqadam/youtube-video-info:dev-master
$details = $video->getDetails();
echo $details->getVideoId();
echo $details->getTitle();
echo $details->getThumbnails();
echo $details->getViewCount();
echo $details->getRating();

这是一个可以返回多条信息的方法：
<?php
extension_loaded('openssl') or die('openssl');
$http['method'] = 'POST';
$http['header'] = 'Content-Type: application/json';
$http['content'] = <<<eof
{
"videoId": "lTGjFpjOIP8", "context": {
"client": {"clientName": "WEB", "clientVersion": "1.19700101"}
}
}
eof;
$con = stream_context_create(['http' => $http]);
$key = '?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8';
echo file_get_contents(
'https://www.youtube.com/youtubei/v1/player' . $key, context: $con
);

从视频网址获取视频ID的功能
function getYTid($ytURL) {
$ytvIDlen = 11; // This is the length of YouTube's video IDs
// The ID string starts after "v=", which is usually right after
// "youtube.com/watch?" in the URL
$idStarts = strpos($ytURL, "?v=");
// In case the "v=" is NOT right after the "?" (not likely, but I like to keep my
// bases covered), it will be after an "&":
if($idStarts === FALSE)
$idStarts = strpos($ytURL, "&v=");
// If still FALSE, URL doesn't have a vid ID
if($idStarts === FALSE)
die("YouTube video ID not found. Please double-check your URL.");
// Offset the start location to match the beginning of the ID string
$idStarts +=3;
// Get the ID string and return it
$ytvID = substr($ytURL, $idStarts, $ytvIDlen);
return $ytvID;
}
进而
$video = getYTid($videourl);
$video_feed = file_get_contents("http://gdata.youtube.com/feeds/api/videos/$video");
$sxml = new SimpleXmlElement($video_feed);
//set up nodes
$namespaces = $sxml->getNameSpaces(true);
$media = $sxml->children($namespaces['media']);
$yt = $media->children($namespaces['yt']);
$yt_attrs = $yt->duration->attributes();
//vars
$video_title = $sxml->title;
$video_description = $sxml->content;
$video_keywords = $media->group->keywords;
$video_length = $yt_attrs['seconds'];
