title: How to Return Riak Objects Sorted by Key Value?
body: <p>I have a bucket called 'employees'.  In it are keys that look like this:</p>
  
  <pre><code>"ryan_07-01-2012_8:15pm"
  "joy_07-02-2012_8:20pm"
  "ryan_07-03-2012_8:30pm"
  "tammy_07-05-2012_8:10pm"
  "tammy_07-11-2012_8:01pm"
  "joy_07-15-2012_8:20pm"
  </code></pre>
  
  <p>All of the keys point to Riak objects that look similar to this:</p>
  
  <pre><code>{ description: "left the office", signed-out: "8:15pm" }
  </code></pre>
  
  <p>In Riak, especially with php client, riak-php, how would you return the objects ordered by time and date based on the key values ( ie "ryan_07-01-2012_8:15pm" ).  </p>
