You can get data from youtube oembed interface in two formats: XML and JSON

您可以从 youtube oembed 接口以两种格式获取数据：XML 和 JSON

Interface address: http://www.youtube.com/oembed?url=youtubeurl&format=json

接口地址：http: //www.youtube.com/oembed?url=youtubeurl&format= json

Use this PHP function to get data

使用这个 PHP 函数来获取数据

 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));

Don't forget to enable extension=php_curl.dllin your php.ini

不要忘记extension=php_curl.dll在您的php.ini

This returns metadata about a video:

这将返回有关视频的元数据：

http://www.youtube.com/oembed?url={videoUrlHere}&format=json

Using your example, a call to:

使用您的示例，调用：

http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=B4CRkpBGQzU&format=json

Returns the following, which you can digest and parse with PHP:

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",

Yet another URL API that can be helpful is: https://www.youtube.com/get_video_info?video_id=B4CRkpBGQzU

另一个有用的 URL API 是：https: //www.youtube.com/get_video_info?video_id=B4CRkpBGQzU

video_id is "v" argument of youTube. Result is a dictionary in URL-encoded format (key1=value1&key2=value2&...)

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&...)

This is undocumented API existing for long time, so exploring it is up to developer. I am aware of "status" (ok/fail), "errorcode" (100 and 150 in my practice), "reason" (string description of error). I am getting duration ("length_seconds") this way because oEmbed does not provide this information (strange, but true) and I can hardly motivate every employer to get keys from youTube to use official API

这是长期存在的未记录的 API，因此开发人员可以自行探索。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，但确实如此）而且我几乎无法激励每个雇主从 youTube 获取密钥以使用官方 API

I know this is an old question but I wrote a package for this purpose, I will put it here maybe someone needs this.

我知道这是一个老问题，但我为此编写了一个包，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();

function to get video id from video url

从视频网址获取视频ID的函数

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;

}

and then

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'];
