Sorting data from an array in PHP

I'm deploying a shipping service to Shopify using a webhook to get this data converted in JSON. I'm trying to send only the fields name, quantity, sku and id in a table.

I'm using foreach function to make it but getting no results.

[fulfillments] => Array
   (
       [0] => stdClass Object
           (
               [line_items] => Array
                   (
                       [0] => stdClass Object
                           (
                               [fulfillment_service] => manual
                               [fulfillment_status] => fulfilled
                               [gift_card] => 
                               [grams] => 2000
                               [id] => 470651995
