Question

我有一个从其他一些函数中检索特定数据的函数。

我遍历检索到的数据并用#字符分解每个结果，数据如下所示：

我想要它，所以每当最后一个索引-1被for循环处理时，代码应该做一个特定的动作，这是我自己的try（函数）：

    public function getDataByVehicle(VehicleType $vehicleType, VehicleOwner $vehicleOwner) {
        $data         = $vehicleType->resolveVehicleTypeWithData($vehicleType);
        $dataKey      = $vehicleType->resolveDataKey($data, $vehicleOwner);
        $dataLocation = $this->data->$dataKey;

        if (is_a($vehicleType, "PassengerCar")) {
            for ($dataLocationIndex = 0; $dataLocationIndex < count($dataLocation); $dataLocationIndex++) {
                $formattedData = explode("#", $dataLocation[$dataLocationIndex]);

                var_dump($formattedData);

                //My own try!
                if (!$dataLocationIndex == count($dataLocation)) {
                    // do action
                }
            }

        }
        return null;
    }

问题

当for循环位于最后一个索引 - 1？

注意

我想使用for循环，因为我希望能够检查数组的下一个索引是什么，如果它不存在，请记住它记住的最后一个。

Answer 1

for循环仅在以下情况下运行：$ dataLocationIndex＆lt; count（$ dataLocation），这意味着你应该检查count（$ dataLocation）减去1，因为循环永远不会达到$ dataLocation的计数。

//My own try!
if ($dataLocationIndex === count($dataLocation)-1) {
    // do action
}

希望它有效。

当for循环处于最后一个索引时执行操作 - 1
