Laravel：在发送电子邮件之前执行查询

Question

我正在使用查询并将记录10一次分块。
查询后，我将使用$ totalOrders并对其进行处理。我想确保该电子邮件呼叫仅发送一次。我是否正确使用此方法，以确保无论有多少个订单，所有->checkStatus都经过了protected function fillOrders() { $totalOrders = []; Order::where('order_status', '!=', Order::FILL) ->limit(3000) ->chunk(10, function ($orders) use (&$totalOrders) { $totalOrders = array_merge($totalOrders, $this->checkStatus($orders)); }); if (count($totalOrders) > 0) { d("How many times does this get fired??"); (new Mailer)->sendOrdersEmail($totalOrders); } } 的处理之后才能到达发送电子邮件的底部？
