title: YouTube api v3 get video category
body: <p>I'm working on a migration of the v2 implementation to v3, but I'm having some difficulty understanding how is API v3 segmented. I'm trying to get the video details from the API but for example, I'm unable to find where the video Category name is stored.</p>
  
  <p>In the v2 implemetation I have: </p>
  
  <pre><code>$title = $info-&gt;entry-&gt;title-&gt;{'$t'};
  $content = nl2br($info-&gt;entry-&gt;{'media$group'}-&gt;{'media$description'}-&gt;{'$t'});
  </code></pre>
  
  <p>and also</p>
  
  <p><code>$info-&gt;entry-&gt;category</code></p>
  
  <p>How would I translate this to the v3 implementation?</p>
  
  <p>currently the api (v2) is quering this:
  <code>http://gdata.youtube.com/feeds/api/videos/</code></p>
  
  <p>What is the v3 equivalent?
  This is a PHP implementation btw.</p>
  
  <p>thanks in advance</p>
