php 选择时间 不跳转刷新数据
各位大神,我简单描述下我的问题

我在当前页面想做两个日期选择器。然后当选择完了日期之后,页面能不跳转刷新表格中的数据。

我知道可以用ajax做。但是我第一次接触php web  所以不太清楚,所以各位在解答的时候尽量详细点。

我先上一下我的页面。



这是还没有加日期选择器的效果图。

我的代码里是这么写的。(因为我代码里现在的时间是写死了。所以肯定要通过选择好的日期,传递值到我这条sql语句里)不知道该如何做。
$top $end 分别是选择器选好的时间。  $data是我的表

<br />$djvhj=mysql_query("select sum(单机率) FROM $data where 日期 between '$top' and '$end'",$connone);<br />


求各位大神给指教!

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
