使用PHP，我怎么可以从YouTube视频网址如标题，说明，缩略图视频信息

http://www.youtube.com/watch?v=B4CRkpBGQzU

Answer 1:

你可以得到的数据从YouTube两种格式透过oEmbed接口：XML和JSON

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

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));

不要忘记启用extension=php_curl.dll在您php.ini



Answer 2:

这将返回关于视频的元数据：

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

使用你的榜样，以一个电话：

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

返回以下，您可以消化和用PHP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
}


Answer 3:

另一个URL的API，它可以帮助是： https://www.youtube.com/get_video_info?video_id=B4CRkpBGQzU

VIDEO_ID是YouTube的影片 “V” 的说法。 结果是在URL编码格式的字典（键1 =值＆键2 =值＆...）

这是现有的很长一段时间未公开的API，所以探索它是由开发商。 我知道的“状态”（OK /失败），“错误代码”（在我的实践中100和150），“理”（错误的字符串描述）。 我得到持续时间（“length_seconds”）这种方式，因为透过oEmbed不提供该信息（奇怪，但真），我也很难激励每一位雇主从YouTube获得的密钥使用官方的API

我写了这个类来显示我们的网站上YouTube视频：

                $testing =parse_url($this->video, PHP_URL_PATH);

                $test = stristr($testing, "/");
                $test = substr($test,1);

            if($youtube_video==true){

                    $play ='<iframe width="'.$this->width.'" height="'.$this->height.'" src="http://www.youtube.com/embed/'.$test.'?rel=0" frameborder="0" allowfullscreen></iframe>';
            }

            if($youtube_list==true){

                $play = $this->error;

        } else {

            // This is not a valid youtube requeust

            $play = $this->error;

        // Return the results        

        return $this->playVideo=$play;
          }

      }

这是你如何使用类： 

   <?php
    include_once("youtube.php");
    $video = new YouTube(320,240);

    // playlist 
    $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;
    ?>

Answer 5:

函数来获取从视频的网址视频ID 

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;

}

然后

$video = getYTid($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'];


Answer 6:

从透过oEmbed： 

$video_url = 'https://www.youtube.com/watch?v=bHQqvYy5KYo';
$url = 'http://www.youtube.com/oembed?format=json&url=' . $video_url;

$json = json_decode(file_get_contents($url), true);
print_r($json); // it will return details of video
