Help with implementing PHP code

Hey WooCommerce team,

I am trying to implement the solution suggested by this user:
https://stackoverflow.com/questions/46688978/how-can-i-get-the-latest-order-id-in-woocommerce

It clearly indicates that the first portion of the code should be in the functions.php

function get_last_order_id(){
    global $wpdb;
    $statuses = array_keys(wc_get_order_statuses());
    $statuses = implode( "','", $statuses );

    // 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);
}

However, where should I be replacing the second half of the code?

$latest_order_id = get_last_order_id(); // Last order ID
$order = wc_get_order( $latest_order_id ); // Get an instance of the WC_Order oject
$order_details = $order->get_data(); // Get the order data in an array

// Raw output test
echo '<pre>'; print_r( $order_details ); echo '</pre>';

I tried placing it in functions.php but it throws up an error message.

Thanks.
