Depending on your version of PHP, the module may come installed as standard so you'll just need to uncomment the line from your php.ini and restart (http://uk2.php.net/manual/en/json.installation.php).

It might be easier just to write the JSON explicitly though, it doesn't look like your code is especially complex.
