How to access a class const dynamically in PHP?

Question

Let's say I have a class like so:

class Order {

    const STATUS_INITIALIZED = 'initialized';
    const STATUS_ORDERED = 'ordered';
}

and I'd like to grab the constant like so:

$status = $_GET['status']; // ?status=STATUS_ORDERED

Is there a way to access the value of the constant, given the name of the constant as a string?

I've tried:

Order::$status
Order::$$status

The function constant does this. The syntax is

constant('Order::'.$status)
