使用PHP，如何从YouTube视频网址获取标题，说明，缩略图等视频信息，例如
http://www.youtube.com/watch?v=B4CRkpBGQzU
答案 0 :(得分：34)
您可以通过两种格式从youtube oembed界面获取数据：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));
不要忘记在extension=php_curl.dll
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，致电：
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对其进行摘要和解析：
{
"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
}

另一个有用的网址API是：https://www.youtube.com/get_video_info?video_id=B4CRkpBGQzU
video_id是＆＃34; v＆＃34; youTube的参数。结果是URL编码格式的字典（key1 = value1＆amp; key2 = value2＆amp; ...）
这是长期存在的未记录的API，因此探索它取决于开发人员。我知道＆＃34;状态＆＃34; （ok / fail），＆＃34; errorcode＆＃34; （在我的练习中为100和150），＆＃34;原因＆＃34; （错误的字符串描述）。我这样得到持续时间（＆＃34; length_seconds＆＃34;）因为oEmbed没有提供这些信息（奇怪，但却是真的）而我很难激励每个雇主从youTube获取密钥以使用官方API

要获取 youtube 个视频description，大小不同的thumbnail，tags等，请使用更新的 v3 em> 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);

我知道这是一个老问题，但是我为此目的编写了一个程序包，我可能会把它放在这里，也许有人需要它。
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();

这里是一个可以返回几条信息的函数。包括我 一些示例属性，但其他可用：
<?php

function youtube_info(string $id_s): object {
$info_s = 'https://www.youtube.com/get_video_info?video_id=' . $id_s;
$get_s = file_get_contents($info_s);
parse_str($get_s, $get_m);
$resp_s = $get_m['player_response'];
return json_decode($resp_s)->microformat->playerMicroformatRenderer;
}
$o = youtube_info('2zPxY5WGG1E');
var_dump(
$o->title->simpleText,
$o->description->simpleText,
$o->thumbnail->thumbnails[0]->url

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;
}
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'];
