        extract($vars);
        // Start collecting output in a buffer
        ob_start();
        require($file);
        // Get the contents of the buffer
        $applied_template = ob_get_contents();
        // Flush the buffer
        ob_end_clean();
        return $applied_template;
    }
}

$final_newsletter = template('letter.php', array('newsletter'=>'The letter...'));
