title: how to sort json string?
body: <p>I want to parse the JSON string below into an associative array, sort it by the 'age' field and output the sorted array as an HTML table:</p>
  
  <pre><code>&lt;?
  $json='[{"name": "jesse","age": 25},{"name": "jason","age": 29},{"name": "johnson","age": 24}]';
  
  ?&gt;
  </code></pre>
  
  <p>Should I use some sort of json_decode to print the individual values and use an existing sorting function in php?</p>
