Loop through WooCommerce order products

functions.php

<?php

$count = 1;
foreach( $order->get_items() as $item_id => $line_item ){
    $item_data = $line_item->get_data();
    $product = $line_item->get_product();
    $product_name = $product->get_name();
    $item_quantity = $line_item->get_quantity();
    $item_total = $line_item->get_total();
    $metadata['Line Item '.$count] = 'Product name: '.$product_name.' | Quantity: '.$item_quantity.' | Item total: '. number_format( $item_total, 2 );
    $count += 1;
}

return $metadata;

How would I get the value of attributes selected on the item?

`
$filters = array(
'post_status' => 'any',
'post_type' => 'shop_order',
'posts_per_page' => 200,
'paged' => 1,
'orderby' => 'modified',
'order' => 'ASC'
);

$loop = new WP_Query($filters);

while ($loop->have_posts()) {
$loop->the_post();
$order = new WC_Order($loop->post->ID);

foreach ($order->get_items() as $key => $lineItem) {

    //uncomment the following to see the full data
    //        echo '<pre>';
    //        print_r($lineItem);
    //        echo '</pre>';
    echo '<br>' . 'Product Name : ' . $lineItem['name'] . '<br>';
    echo 'Product ID : ' . $lineItem['product_id'] . '<br>';
    if ($lineItem['variation_id']) {
        echo 'Product Type : Variable Product' . '<br>';
    } else {
        echo 'Product Type : Simple Product' . '<br>';
    }
}

}`
