PHP Array - Array Returns Value, And a 0

Question

So I got this array:

$list = simplexml_load_file('http://feu01.ps4.update.playstation.net/update/ps4/list/eu/ps4-updatelist.xml');

if($list) {
    $data = array('firmware' => $list->region->system_pup[0]['label']);

    header('Content-Type: application/json');

    echo json_encode($data);
}

And it outputs this:

{"firmware":{"0":"5.01"}}

But there's also a zero there. How do I remove it from the array so it's like this:

{"firmware":"5.01"}

This is a SimpleXMLElement result which you need to convert to a string if you want that data:

$data = array('firmware' => (string) $list->region->system_pup[0]['label']);

In JSON form it looks like an associative array, which it isn't, so the [0] trick which normally works to navigate to it won't.

I've updated the answer. Note that using var_dump showed what this result actually was, so if you're ever stumped, try that first.

@FirstOne I think the {'0'=>...} stuff is just an ugly artifact of how SimpleXMLElement is implemented.
