推荐答案

由于 YouTube v2 API 即将弃用，这里有一个更新的解决方案.

1. 首先在此处
克隆 Google API PHP 客户端
2. 接下来，您需要通过创建一个新项目向 Google 此处注册一个应用程序，在API 和身份验证 → API"部分下打开 YouTube 数据 API，以及
3. 在API 和身份验证 → 凭据"下创建一个新的 OAuth 客户端 ID，并将完整路径添加到您的重定向 URI 列表中.(即http://example.com/get_youtube_duration.php)
4. 使用此代码(改编自this 示例代码)，同时确保使用您自己的值填写 $OAUTH2_CLIENT_ID 和 $OAUTH2_CLIENT_SECRET 变量第 3 步.
5. 硬编码 $videoId 变量的值或使用 video_id 获取参数设置它(即 http://example.com/get_youtube_duration.php?video_id=XXXXXXX)
6. 访问您的脚本，点击链接以授权应用程序并使用您的 Google 帐户获取令牌，该令牌会将您重定向回您的代码并显示持续时间.

1. Start by cloning the Google API PHP Client here
2. Next, you'll want to register an application with Google here by creating a new Project, turning on the YouTube Data API under the "APIs and auth → API" section, and
3. Create a new OAuth Client ID under "APIs and auth → Credentials" and add the full path to your redirect URI list. (i.e. http://example.com/get_youtube_duration.php)
4. Use this code (which was adapted from this sample code), while making sure to fill in the $OAUTH2_CLIENT_ID and $OAUTH2_CLIENT_SECRET variables with your own values from step 3.
5. Hardcode a value for the $videoId variable or set it using the video_id get parameter (i.e. http://example.com/get_youtube_duration.php?video_id=XXXXXXX)
6. Visit your script, click the link to authorize the app and use your google account to get a token, which redirects you back to your code and will display the duration.

这是您的输出:

Video Duration

0 mins

29 secs

一些额外的资源:https://developers.google.com/youtube/v3/docs/视频#contentDetails.durationhttps://developers.google.com/youtube/v3/docs/videos/列表

基于提要中只有一个持续时间元素的假设，这对我有用.

This worked for me based on the assumption that there is only one duration element in the feed.

<?php

$vidID="voNEBqRZmBc";
//http://www.youtube.com/watch?v=voNEBqRZmBc
$url = "http://gdata.youtube.com/feeds/api/videos/". $vidID;
$doc = new DOMDocument;
$doc->load($url);
$title = $doc->getElementsByTagName("title")->item(0)->nodeValue;
$duration = $doc->getElementsByTagName('duration')->item(0)->getAttribute('seconds');

print "TITLE: ".$title."<br />";
print "Duration: ".$duration ."<br />";

输出:

TITLE: Introducing iTime
Duration: 29
