Php 如何减少laravel中的长处理时间

我使用Laravel 5.7构建了一个员工管理系统。计算工资对于100-150名员工来说效果很好（但处理数据需要很长时间）&对于150多名员工来说，它显示出超时错误

我想添加一个功能，一次计算所有员工的工资，同时减少处理时间。使用chunk（）是否合适？如果是，我如何实施

注意： web应用程序是针对BPO的，因此在计算工资时有许多类型的逻辑可以应用。代码太长，无法在此处共享，但如果有人想查看代码，我可以共享

---

这是一个巨大的过程，一次完成许多事情，其中一些事情彼此嵌套得很深

这个函数非常长，这意味着它可能需要抽象成各种方法和类（更好的OOP）

在一些Laravel查询中，您可能也遇到了N+1问题，尽管很难一目了然

我建议使用Laravel的队列，并将每位员工的工资计算添加到队列中：

然后，您可以使用辅助进程单独执行每一个

所有的数据库更新和事务都意味着PHP不断地从您的数据库来回移动。尝试用纯代码执行尽可能多的操作，然后完成后写入数据库。（在可能的情况下，这不是一条综合规则）

最初我会说，考虑用<代码> > GETAtAddicSee（）/<代码>和<代码> CalpSaleFaluMePayEEAdDeCon（）/<代码> < < /P>方法创建<代码> SalayCalp计算器< /代码>类。
另外，创建一个CSV导出器类。首先处理所有工资计算，将结果存储在数据库中，然后根据需要转换为CSV
当你能够查看所有不同的部分后，你会重构它，其他人可能会提出更好的分解方法，但在某些方面没有正确的答案。。。只要从OOP和方法抽象开始，它就会变得更好

使用
microtime（true）
获取并计算开始和完成操作之间的时间差，开始跟踪每个函数运行多长时间。。。然后首先去寻找大的优化。最慢的部分是什么？为什么?

您可能会问十几个堆栈溢出问题来优化这些方法中的每一个，这没关系
 请分享代码除非你诚实地发布代码，否则很难推荐优化。您是否做过任何分析以查看流程的哪些部分花费的时间最多？您可能会在这里发现一些有趣的东西，特别是这个简单分析的答案您是在浏览器中还是在控制台中运行它？如果在浏览器中运行，最简单的方法是在php.ini中增加最大执行时间。当然，更好的方法是优化代码，但在这种情况下，您应该与我们共享。在没有看到任何代码和对系统一无所知的情况下，可能还有另一种方法。如果你想报告历史数据，那么你可以从生成的工资单中获取数据，然后根据这些数据生成报告。谢谢你的精彩解释。我已经在共享的函数中使用了另外6个函数，例如GetAttention（）、get\u word\u days（）、get\u shift\u start\u end（）&更多。不管怎样，我也会尝试一下Laravel队列和分析谢谢@DeepikaSoni在你发布的任何新问题中随时给我贴标签，我很好奇这一切是怎么回事！
