Laravel：在处理数据后使用外部变量？

Question

我有一个函数，我从数据库中获取订单，然后使用它们一次转到10个。如果我有100个订单，我相信会发生的流程是get将被调用10次（因为有100个订单）。现在，一旦完成，我希望能够访问 $totalOrders.这可能吗？getUnfilledOrderschunkcheckStatuscheckStatusgetUnfulfilledOrdersprotected function getUnfulfilledOrders(){    Order::where('order_status', '!=', true)        ->where('tracking_number', '!=', null)        ->limit(3000)        ->chunk(10, function ($unfulfilledOrders) {            $this->checkStatus($unfulfilledOrders);        });   // how to do something now with $totalOrders once ALL Orders are processed 10 at a time;}protected function checkStatus($unfilledOrders){    $totalOrders = array();    foreach ($unfulfilledOrders as $unfulfilledOrder) {         // logic here         array_push($totalOrders, $unfulFilledOrder->id);    }}

Answer 1

喜欢这个：

protected function getUnfulfilledOrders()

{

    $totalOrders = [];

    Order::where('order_status', '!=', true)

        ->where('tracking_number', '!=', null)

        ->limit(3000)

        // Add use (&$totalOrders)

        ->chunk(10, function ($unfulfilledOrders) use (&$totalOrders) {

            $totalOrders = array_merge($totalOrders, $this->checkStatus($unfulfilledOrders));

        });

   // how to do something now with $totalOrders once ALL Orders are processed 10 at a time;

}

protected function checkStatus($unfilledOrders)

{

    $totalOrders = array();

    foreach ($unfulfilledOrders as $unfulfilledOrder) {

         // logic here

         array_push($totalOrders, $unfilledOrder->id);

    }

    // Return the generated array

    return $totalOrders;

}

在这里，我在开始时启动了一个空数组，并将 返回的任何内容合并到其中。getUnfulfilledOrders()checkStatus()
