title: How to do a query in Yii with multiple primary key values
body: <p>So I have a simple language model whose database structure looks something like this:</p>
  
  <pre><code>id | language
  _____________
  
  1  | english
  2  | japanese
  3  | russian
  4  | german
  5  | thai
  </code></pre>
  
  <p>Say I have a list of comma separated values for languages that an object has ( i.e. 1,4,5). How would I do a database query using Yii and return (1,4,5) into an array with (english, german, thai)?</p>
