Php 如何在没有向数据库添加任何内容时触发Laravel中的事件，而不是在更新数据库时发出警报？

我正在Laravel上构建一个简单的拍卖解决方案。下面的代码是一些提取的测试代码，假设它充当拍卖人

问题是，当它运行时，它会锁定对Auctionbid Postgres表的访问，用户不能在运行时出价。我的测试是在本地主机上进行的，在拍卖中运行一些用户，以及在同一个盒子/同一个IPtrigger上运行拍卖过程（“竞价频道”、“竞价警告”和$message）； } 如果（$bidIncrementResetCounter==2）{ $message=“一次……两次……”； $pusher->trigger（'bids\u channel'，'bid warning'，$message）； } 如果（$bidIncrementResetCounter==3）{ $message=“我们有赢家！”； $pusher->trigger（'bids\u channel'，'bid warning'，$message）； 打破 } $bidIncrementResetCounter++； }否则{ $bidIncrementResetCounter=0； } } 否则{ $currentWinnerId=0； } $lastBidderId=$currentWinnerId； $lastBidderBidAmount=$currentWinnerBidAmount； 睡眠（10）//
