我目前正在开展一个项目并遇到一个我目前无法解决的挑战。我已经尝试了很长时间，并且最终将我的场景放在这里，因为我可以得到一些有用的提示。另外，请耐心等待，因为我将详细介绍这个问题。
所以，我有一个项目，其中包含根据班次时间（时间为24小时格式）计算员工工资的模块。现在，工资率根据工作时间（周一至周五）的时间而有所不同，工资率分为两部分：Week Day和Week Night.此外，weekend（星期六和星期日）的工资率也与正常天数不同。最后，有public holidays，他们也有不同于其他事件的工资率。下表显示了工资率摘要：
------------------------------------------
|Event | Shift Times |
------------------------------------------
|Week Day | 0600-1800 |
------------------------------------------
|Week Night | 1800-0600 |
------------------------------------------
|Weekend | All day weekend rate |
-------------------------------------------
|Public holiday|All day public holiday rate|
-------------------------------------------+
现在，如果您只需要为该特定日期分配工资率，例如轮班是在公共假期然后分配公共假期费率，那么这看起来非常简单，但问题是我的项目不是这种情况。
工作原理
现在，这种转变通常为12小时，可以介于两种不同的工资率之间，例如，一位员工从0900开始，在2100完成Monday。因此，按week day付费率计算小时数为9小时，week night付费率为3小时。同样，员工可以采用三种不同的工资率进行转移，例如：班次从2200周日晚开始，到0900早晨结束Monday。因此，由于周日晚上的班次开始和2小时后的周末结束，付费率小时将是weekend费率的2小时。因此，从0000到0600（6小时），工资率将基于week night费率，其余时间则在工作日之下。
现在好消息是我能够做到现在为止。一切都很完美。虽然我已经把很多条件放在里面，我认为这不是一个好习惯但是暂时我想让它运行起来。 Public Holiday发生时会出现问题。现在，公共假期是最困难的部分，因为它可以在任何一天（工作日和周末）进行，并且必须在每种情况下重新检查，并且必须进行加工和减少时间太复杂且不起作用。如果整个班次属于公众假期，我能够做到这一点。但是，当它下降超过一个支付率类别时，我就很难解决问题。我不会分享公共假期的一个代码，因为代码太复杂而且你可能会感到困惑。但是，我将分享其他付费率格式工作正常的代码。
注意 我建议你不要从我的代码中得到任何想法，因为我想要你的建议，如果你查看我的代码，你可能会用尽想法。

好的是，数据库中没有任何东西出来。这个问题基于完全的思维计算和技术，并且开发了纯PHP。
请高度赞赏这方面的任何帮助。 感谢。
