parsing xml array response in PHP objects

Question

i am working on a UPS tracking API, i have called the API to track the package, i am getting the right response, but in array format, i am new to json decoding, please tell me how to parse this in PHP, do i have to create multiple objects in PHP? i am attaching the output as well as the PHP code.

PHP Code

if (isset($_POST['af0'])) {
    if (preg_match('/^[a-z\d_]{4,80}$/i', $_POST['trackingNumber'])) {
        $cleanTrackingNumber = $_POST['trackingNumber'];
        $someArray = upsTrack("$cleanTrackingNumber");
        echo '<pre>'; print_r($someArray); echo '</pre>';

    } else {
        echo 'Invalid tracking number... sigh...';
    }
}

Output

If you already have the output in Array format then you don't have anything more to do with json decoding.

You can use $someArray to get any data from the array. It's up to you if you want to just display it or save it, for example in a database.

What is it you trying to accomplish?
