Question

所以我有一个变量，如果我var_dump可以得到一个大数组。我正在尝试获得以下信息：

["name"]=> string(26) "Online marketing Duitsland"

整个数组的结果如下：

array(1) { 
  [33]=> object(WC_Order_Item_Product)#9730 (11) { 
    ["extra_data":protected]=> array(9) { 
      ["product_id"]=> int(0) 
      ["variation_id"]=> int(0) 
      ["quantity"]=> int(1) 
      ["tax_class"]=> string(0) "" 
      ["subtotal"]=> int(0) 
      ["subtotal_tax"]=> int(0) 
      ["total"]=> int(0) 
      ["total_tax"]=> int(0) 
      ["taxes"]=> array(2) {

    }

  } 
}

如何获得特定部分？

Answer 1

使用get_name（）方法

$var[33]->get_name();

https://docs.woocommerce.com/wc-apidocs/class-WC_Order_Item.html#_get_name

Answer 2

可以尝试：-

echo $arr[33]->data->name;

或尝试：-

 $arr = (Array)$arr;//cast the object as an Array
 echo $arr[33]["\0*\0" . 'data']['name'];
