PayPal REST API 获取总金额

Question

我正在使用最新版本的 PayPal rest-api-sdk-php。在创建付款和执行付款以及取回所有相关数据方面一切正常，但我决定我想要通过贝宝支付的总金额。它返回一个 JSON 对象，示例如下

"transactions": [
    {
        "amount": {
            "total": "20.00",
            "currency": "GBP",
            "details": {
                "subtotal": "17.50",
                "tax": "1.30",
                "shipping": "1.20"
            }
        },
        "description": "Payment description",
        "invoice_number": "55e30dbd55cea",
        "item_list": {
            "items": [
                {
                    "name": "Ground Coffee 40 oz",
                    "price": "7.50",
                    "currency": "GBP",
                    "quantity": "1",
                    "description": "Ground Coffee 40 oz",
                    "tax": "0.30"
                },
                {
                    "name": "Granola bars",
                    "price": "2.00",
                    "currency": "USD",
                    "quantity": "5",
                    "description": "Granola Bars with Peanuts",
                    "tax": "0.20"
                }
            ]
        },
    }
],

我曾尝试调用 $payment->transactions->amount->total 但出现错误。只是想知道是否有人可以提供一些启示。谢谢

"transactions" 是一个数组，所以你需要遍历它。 如果您想要第一个总金额，请尝试 $payment->transactions[0]->amount->total;
