我正在试验我的第一个API，并对结果感到困惑。我得到一个数组返回:
Array
(
[GetOrderListResult] => Array
(
[Status] => Success
[MessageCode] => 0
[ResultData] => Array
(
[OrderResponseItem] => Array
(
[0] => Array
(
[NumberOfMatches] => 2
[OrderTimeGMT] => 2014-05-05T03:23:00
[LastUpdateDate] => 2014-05-28T11:41:45.953
[TotalOrderAmount] => 12.7800
[OrderState] => Active
[DateCancelledGMT] =>
[OrderID] => 138711
[ClientOrderIdentifier] => 138711
[SellerOrderID] =>
[OrderStatus] => Array
(
[CheckoutStatus] => NotVisited
[CheckoutDateGMT] => 1900-01-01T00:00:00
[PaymentStatus] => NotSubmitted
[PaymentDateGMT] => 1900-01-01T00:00:00
[ShippingStatus] => Unshipped
[ShippingDateGMT] => 1900-01-01T00:00:00
[OrderRefundStatus] => NoRefunds
)
)
[1] => Array
(
[NumberOfMatches] => 2
[OrderTimeGMT] => 2014-05-05T03:23:00
[LastUpdateDate] => 2014-05-28T12:59:01.78
[TotalOrderAmount] => 6.3900
[OrderState] => Active
[DateCancelledGMT] =>
[OrderID] => 138750
[ClientOrderIdentifier] => 138750
[SellerOrderID] =>
[OrderStatus] => Array
(
[CheckoutStatus] => NotVisited
[CheckoutDateGMT] => 1900-01-01T00:00:00
[PaymentStatus] => NotSubmitted
[PaymentDateGMT] => 1900-01-01T00:00:00
[ShippingStatus] => Unshipped
[ShippingDateGMT] => 1900-01-01T00:00:00
[OrderRefundStatus] => NoRefunds
)
)
)
)
)
)
现在我知道如何在数组中引用一个字段(如订单id)的唯一方法是:
echo "Order ID: ".$result['GetOrderListResult']['ResultData']['OrderResponseItem']['0']['OrderID'];
但是我想能够循环通过数组的订单和执行每个项目的代码，有人可以指出我在正确的方向:
a)是否有更好的方法来引用这些字段?b)我如何循环通过数组的OrderResponseItem部分?
我能想到的唯一循环是针对整个数组，而不是数组中嵌套的项。
抱歉，如果我错过了一些简单的....
谢谢，如果您需要其他格式的数据，请告诉我。
既然您已经知道键，您可以使用foreach来访问它们并指向该键然后循环。像这样:
foreach($result['GetOrderListResult']['ResultData']['OrderResponseItem'] as $value) {
$order_id = $value['OrderID'];
// your other processes
}
