从响应中提取空值

Question

我正在尝试从此响应中提取 PHP 的价值{    "id": "pi_1FxfIlJtivvUT2vVGgfaIWIZ",    "object": "payment_intent",    "last_payment_error": "",    "livemode": "",    "next_action": "",    "status": "succeeded",    "amount": 538,    "charges": {        "object": "list",        "data": [{            "id": "ch_1FxfImJtivvUT2vVs7YQPJUb",            "object": "charge",            "amount": 538        }]    }}当我尝试：$payment_intentID = $payment_intent->id;它有效，但是当我尝试时：$payment_intentID = $payment_intent->charges->data->id;我得到空有什么问题？谢谢，问候

Answer 1

$payment_intent->charges->data是一个数组 - 试试这个：

$payment_intent->charges->data[0]->id
