关于$row中的计算
员工编号、姓名、no、物件名称、行驶距离、到达时间、出发时间可通过数据库 $row['']直接获取
行驶时间、行驶速度、作业时间需要进行计算获取
作业时间我是这样获取的
行驶速度的获取
问题1:这个行驶时间用excel来描述的话例如zhangsan的no=2的行 为 I3-J2 以此类推I4-J3,I5-J4,。。这个能不能进行处理,有没有什么$row+1错行计算的方法?
问题2:要求是按姓名分组 这里是不是用group by比较好?如果用order by可以吗?
问题3:每个人之后,还要有合计,例如需要计算行驶距离的和、行驶时间的和、作业时间的和,这部分要如何处理?
问题4:整个工作内容是不是用PHPEXCEL更容易处理一些?
谢谢

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
