What exactly does the $request_filename variable of Nginx conf mean?

For example
example.com/index.php
Example.com/index.php?a=3
Example.com/index.php/a/b/c

example.com/test.php
Example.com/test.php?a=3
Example.com/test.php/a/b/c

What is the request_filename of these URLs?

$request_filename 就是请求资源的路径啦~~例如你这里，应该对应的是 root下的 index.php 和 test.php当然还有看前面有没有伪静态规则什么的。。。
