Analytics PHP API and Headers Error (no replies)

I am integrating Piwik analytics api into a YII framework project and I am having a specific issue with api requests changing headers for my output. Here is the class that I started to build so you can see how I am calling the libraries. I am getting the response just fine, but it is converting my entire output from the view file to text. I can see the headers have been changed. Something about the way I am calling it is changing the headers. I can't find information on how to turn this off or modify it with ob_flush(). Any help would be very much appreciated.


<?php

class YiiPiwik {
function __construct() {
define('PIWIK_INCLUDE_PATH', __DIR__ .'/library');
define('PIWIK_USER_PATH', __DIR__ .'/library');
define('PIWIK_ENABLE_DISPATCH', false);
define('PIWIK_ENABLE_ERROR_HANDLER', false);
define('PIWIK_ENABLE_SESSION_START', false);

require_once PIWIK_INCLUDE_PATH . "/index.php";
require_once PIWIK_INCLUDE_PATH . "/core/API/Request.php";

include_once PIWIK_INCLUDE_PATH.'/core/Loader.php';
spl_autoload_unregister(array('YiiBase','autoload'));
spl_autoload_register(array('Piwik_Loader','autoload'));
spl_autoload_register(array('YiiBase','autoload'));
Piwik_FrontController::getInstance()->init();
}

public function Analytics() {



$request = new Piwik_API_Request('method=API.getPiwikVersion&format=php&token_auth=axxx&serialize=1 ');


$requestAnswer = $request->process();



return $requestAnswer;

}
