How to get cart details from the order id in woocommerce?

I would like to get the complete cart details from the Woocommerce order I d including the totals and subtotals etc. How to approach?

You can get the complete cart details by using the global $woocommerce object.

global $woocommerce;
$items = $woocommerce->cart->get_cart();

Or you can use the WC() function directly to access the cart details.

$items = WC()->cart->get_cart();
