How to access protected data in Woocommerce? - php

Question

I am using this to get the data from the latest completed order:
<?php
function get_last_order_id(){
global $wpdb;
$statuses = "wc-completed";
// Getting last Order ID (max value)
$results = $wpdb->get_col( "
SELECT MAX(ID) FROM {$wpdb->prefix}posts
WHERE post_type LIKE 'shop_order'
AND post_status IN ('$statuses')
" );
return reset($results);
}
$latest_order_id = get_last_order_id(); // Last order ID
echo ($latest_order_id);
$order = wc_get_order( $latest_order_id );
$order_data = $order->get_data();
print_r($order);
However, the data that I need to get is showing as this:
[data:protected] => Array ( [id] => 3767 [key] => billing_name [value] => David) )
I have searched the questions on the StackOverflow on this but unfortunately, I still can't access this. Does anyone have an idea of how I can get it?
Thanks in Advance

<?php
function get_last_order_id(){
global $wpdb;
$statuses = "wc-completed";
// Getting last Order ID (max value)
$results = $wpdb->get_row( "SELECT MAX(P.ID) ,PM.meta_value as firstname
FROM {$wpdb->prefix}posts AS P
INNER JOIN {$wpdb->prefix}postmeta AS PM
ON P.ID = PM.post_id
WHERE P.post_type LIKE 'shop_order'
AND P.post_status IN ('$statuses')
AND PM.meta_key='_billing_first_name'" );
return $results;
}
$latest_order_id = get_last_order_id(); // Last order ID
$firstname = $latest_order_id->firstname;
echo $firstname;
