using magento as php framework i create a controller displaying the following information

    public function bynumberAction(){
        $t = new \RocketShipIt\Track('fedex');
        $response = $t->track('770190256519');

//        parse results
        $events['C'] = $response['A']['B']['C'];
        $events['D'] = $response['A']['B']['D']
        $events['E'] = $response['A']['B']['E']

//        serve results
        $this->loadLayout( array('default','shipping_track_bynumber'));
        $this->_initLayoutMessages('customer/session');
        $this->getLayout()->getBlock('track_bynumber')
                ->setCollection($events)
                ->setTemplate('shipping/track/bynumber.phtml');
        $this->renderLayout();
    }

On the frontend phtml (bynumber.phtml) file I put:

<?php $res = $this->getCollection() ?>

<?php foreach ($res as $row) {echo $row['C'] . ' ' . $row['D'] . ' ' . $row['E'] . '<br />';} ?>

No information is displayed.. any help appreciated. brgds

There are more issues. First of all, there is a syntax error - missing semicolon after a command on lines 6 and 7 of function bynumberAction.

Second: why do you have different array structure in your controller, if you know how the response looks?

You use: $response['A']['B']['C'];

Response looks: $response['Data']['A']['B']['0']['C'];

Try this in your controller:

$events = array()
foreach ($response['Data']['A']['B'] as $data)
{
    $events[] = $data;
}

...and in a template:

foreach ($res as $row) { echo $row['C']['value'] ... }
