     },
     "created":1322700852,

     "disputed":false,
     "fee":0,
     "id":"ch_00000000000000",
     "livemode":false,
     "object":"charge",
     "paid":true,
     "refunded":true
  }
 },
 "id":"evt_00000000000000",
"livemode":false,
"type":"charge.refunded"
 }

Answer 1

看起来你只是缺少指向object对象的指针：

$amount = $event_json->data->object->amount;

Answer 2

data内部元素称为object，amount是object的一部分，因此您可能需要使用

 $amount =  $event_json->data->object->amount ;
