How can I get this Json value in Stripe Invoice? - php

Question

I am able to retrieve the first 4 values fine, but $item_name is eluding me. What is wrong with the syntax I'm using to retrieve the plan: name: "LITE" value
this is my php - the first 4 return fine but $item_name returns invalid.
$customer = $event_json->data->object->customer;
$amount = $event_json->data->object->total;
$period_end = $event_json->data->object->period_end;
$paid = $event_json->data->object->paid;
$item_name = $event_json->data->object->lines->data->plan->name;
and this is what is being sent from Stripe

Data is an array:
$item_name = $event_json->data->object->lines->data[0]->plan->name;
Right?
