title: Returning PHP Multi-Dimension Array to Javascript/AJAX
body: <p>My understanding is that in order to return a complex PHP variable to Javascript, it should be done via AJAX and json_encode.  Could somebody give me an actual example (both PHP and Javascript code) of this?  Lets say we have the two-dim array in PHP:</p>
  
  <pre><code>$twoDArr = array( array('Greg', 44, 'Owner'),
                    array('Joe', 23, 'Renter'),
                    array('Susan', 39, 'Owner'),
                    array('John', 32, 'Renter)
                  );
  </code></pre>
  
  <p>How would we return this to an analogous two dimensional array in javascript using json_encode? </p>
