title: PHP get MongoDBRef with query
body: <p>I was wondering if there is a way to perform a find() and have Mongo automatically return the associated references without having to run getDBRef() once the parent record has been returned.</p>
  
  <p>I don't see it anywhere in the PHP documentation. I can easily support using getDBRef but it doesn't seem as efficient as it could be.</p>
  
  <p>Also...I'm surprised there's no way to select the specific data to return in the linked reference. I may as well just perform another manual find statement so I can control what the return is...but there <em>has</em> to be a more performance oriented way to do this.</p>
  
  <p>Perhaps I should change my methodology and instead of using the PHP library classes for find, generate my own JavaScript command and run it using the MongoCode class? Would that work and if so...I'm wondering what it would look like. <em>scratches head then heads to The Google</em></p>
  
  <p>Thanks!</p>
