Oh, I should add that the json_decode() function doesn't exist in PHP 5.1. It's native in 5.2.

You can use PEAR to install the class from here:

http://pear.php.net/package/Services_JSON

And then rig your own json_decode() function like so:

function json_decode($content, $assoc=false){
                require_once '<PATH TO JSON.php>';
                if ( $assoc ){
                    $json = new Services_JSON(SERVICES_JSON_LOOSE_TYPE);
        } else {
                    $json = new Services_JSON;
                }
        return $json->decode($content);
    }
