Php 在购物车和结账页面中显示变体数组

我正在尝试向购物车添加一些自定义数据。为此，我使用了

   $woocommerce->cart->add_to_cart($domainProductId, $period, 0, array('Domain Name' => $domain, 'Domain Term' => $period));

当我尝试在另一个函数或另一个页面上显示购物车详细信息时，输入的详细信息显示在变体数组中

    global $woocommerce;
    $items = $woocommerce->cart->get_cart(); 
    echo "<pre>"; print_r($items);

global$woodcommerce；
$items=$woocommerce->cart->get_cart（）；
回声“；打印（项目）；

项目数组是

数组
