Как получить данные из массива php?

Question

[Denis]

Здравствуйте

Подскажите, пожалуйста, как получить данные из такого массива. Именно что хранится в @meta_data@

Изначально пробовал вызывать через цикл

foreach ($data['line_items'] as $meta) {
	echo '<pre>';
	var_dump($meta['meta_data']);
       echo '</pre>';
}

Но он выдает NULL

object(WC_Order_Item_Product)#18707 (11) {

  array(9) {
    ["product_id"]=>
    int(0)

Вы обращаетесь с ним как с массивом, а это объект. У него должен быть свой метод для получения данных, например:

$metaData = $meta->get_data();
var_dump($metaData['meta_data']);
