Answer 1

You can use the data API to get the information for a video. You might need to extract the video's identifier from the URL.

http://code.google.com/apis/youtube/2.0/developers_guide_php.html#Retrieving_Video_Entry

If you're using Zend, there's already a class to do the heavy lifting:

<?php
require_once 'Zend/Loader.php'; // the Zend dir must be in your include_path
Zend_Loader::loadClass('Zend_Gdata_YouTube');
$yt = new Zend_Gdata_YouTube();
$videoEntry = $yt->getVideoEntry('the0KZLEacs');
$duration = $videoEntry->getVideoDuration();

If not, you can go to http://gdata.youtube.com/feeds/api/videos/{$videoId} and get an XML document to process yourself.

For example, http://gdata.youtube.com/feeds/api/videos/KURI9EQV3dY returns an XML document for a video which contains information including the duration: <yt:duration seconds='153'/>

Answer 2

Per their docs, In a video feed entry, the <yt:duration> tag specifies a video's length.
