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？getUnfilledOrderschunkcheckStatuscheckStatusgetUnfulfilledOrders

protected 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);

    }

}

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()
