how i can retrieve all woocommerce orders

Answer

WooCommerce already provided API to get all orders https://example.com/wp-json/wc/v3/orders

For more details please see the documentation

If you want function based instead of REST API then, please do like this:

You should call your order function into the action hook woocommerce_after_register_post_type to work properly. So please enclose your function call like this:

add_action(
    'woocommerce_after_register_post_type', 
    function() {
        $orders = wc_get_orders( array( 'numberposts' => -1 ) );
        var_dump( $orders );
    }
);

---

Then you can loop through the object and fetch all the necessary details for e.g.

foreach ( $orders->get_items() as $item_id => $item ) {
   $product_id = $item->get_product_id();
   $variation_id = $item->get_variation_id();
   $product = $item->get_product();
   $name = $item->get_name();
   $quantity = $item->get_quantity();
   $subtotal = $item->get_subtotal();
   $total = $item->get_total();
   $tax = $item->get_subtotal_tax();
   $taxclass = $item->get_tax_class();
   $taxstat = $item->get_tax_status();
   $allmeta = $item->get_meta_data();
   $somemeta = $item->get_meta( '_whatever', true );
   $type = $item->get_type();
}
