wordpress - Woocommerce - php to get order information -

i'm trying data associated order on woocommerce plugin (wordpress). currently, have written own plugin contains code:

<?php  global $woocommerce; $order = new wc_order($order_id); $order_shipping_total = $order->get_shipping(); echo $order_shipping_total; ?> 

this test out, don't believe working- need list of orders have order status, , able access fields(like first name) each order in list. how go doing this? also, files include make work? class-wc-order() file?

recently worked export of orders data in xml.

$args = array(   'post_type' => 'shop_order',   'post_status' => 'publish',   'meta_key' => '_customer_user',   'posts_per_page' => '-1' ); $my_query = new wp_query($args);  $customer_orders = $my_query->posts;  foreach ($customer_orders $customer_order) {  $order = new wc_order();   $order->populate($customer_order);  $orderdata = (array) $order;   // $orderdata array have information. e.g shippin firstname, lastname, address ... , more.... enjoy! }
