Big Help implementing this Factory pattern in CodeIgniter

[eluser]crumpet[/eluser]

Code:

$style = 'formal'; // OR 'casual'
$data['body'] = "thanks for lunch";
$data['name'] = "Jason";
$this->load->view($style . '/header');
$this->load->view($style . '/body', $data);
$this->load->view($style . '/footer', $data);

//dir structure
//  views ->
//     ->formal
//         -> header.php, body.php, footer.php
//     ->casual
//         ->header.php, body.php, footer.php

Personally i'd just have a letter.php for each style which contains header, body and footer
