推荐答案

由于HTTP是无状态协议，因此每个PHP脚本都是在一个单独的上执行的HTTP请求。要计算它们，您需要有一些持久对象来累积某个主题的请求数（在某些约束下，无论它是什么）。此类对象可以是服务器端的文件或数据库。在每个请求中，您打开一个文件，读取值，递增它并将文件写回。或修改数据库中的值。

As HTTP is a stateless protocol, each of your PHP scripts is executed on a separate HTTP request. To count them, you need to have some persistent object to accumulate the number of requests on a certain topic (under certain constraints, whatever it is). Such object could be a file on your server side or a database. On each request, you open a file, read the value, increment it and write the file back. Or modify a value in your database.
