php => rails (JSON)

I have an application that creates a snippet of php in a server, for
packaging up data for JSON, using the php package "Pear." The snippet
I create (with varying data, of course, as the application runs) is
written in php, but I really want to keep things rails-centric. Is
there a way to convert this to NOT use php, so that I am entirely Ruby
on Rails? Thanks, Janna B

<?php
ini_set('include_path',ini_get('include_path').";C:\Program Files
\Apache Group\Apache2\htdocs"."\pear");
require('JSON.php');

$records=array();
$records[]=array('order'=>1, 'username'=>'joeyt');
$json=new Services_JSON();
echo($json->encode($records));
?>
