title: JSON transformation for PHP
body: <p>Is there any reliable standardized way to transform JSON on the server side? (JSONT perhaps)</p>
  
  <p>Can't really think of a way to use XSLT for that, or is there?</p>
  
  <p>Edit: I should've been more specific. A somewhat standardized transformation is what I'm looking for: using json_decode and json_encode doesn't do that, it converts between formats. Converting one JSON string into another is what I'm curious about. </p>
