Как я могу получить информацию о видео YouTube с URL-адреса видео с помощью PHP?

Вы можете получить данные с веб-интерфейса youtube в двух форматах: XML и JSON

Адрес интерфейса: http://www.youtube.com/oembed?url=youtubeurl&format=json

Используйте эту функцию PHP для получения данных.

  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)); 

Не забудьте включить extension=php_curl.dll в php.ini

Это возвращает метаданные о видео:

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

Используя ваш пример, вызов:

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

Возвращает следующее, которое вы можете переваривать и анализировать с помощью PHP:

 { "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 } 

Еще один API-интерфейс URL, который может быть полезен: https://www.youtube.com/get_video_info?video_id=B4CRkpBGQzU

video_id – это аргумент «v» youTube. Результат – это словарь в формате URL-кодирования (key1 = value1 & key2 = value2 & …)

Это недокументированный API, существующий в течение длительного времени, поэтому его изучение зависит от разработчика. Я знаю «статус» (ok / fail), «errorcode» (100 и 150 в моей практике), «причина» (строковое описание ошибки). Я получаю продолжительность («length_seconds») таким образом, потому что oEmbed не предоставляет эту информацию (странно, но верно), и я вряд ли могу мотивировать каждого работодателя получить ключи от youTube для использования официального API

Я написал этот класс, чтобы отобразить видео на Youtube на нашем веб-сайте:

И вот как вы можете использовать класс:

  <?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; ?>

функция для получения идентификатора видео с видео URL

 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; } 

а потом

 $video = getYTid($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']; 

От 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
