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
