如何使用PHP获取Apache AccessFileName值？

I have a custom AccessFileName setup for my virtual host. How can I get that variable via code?

I've looked at the $_SERVER variables available but it doesn't have the AccessFileName listed as an available variable.

I do need to have this AccessFileName setting different for different virtual hosts so if I can do this without updating php.ini that would be ideal.

If you can add this option to virtualhost config, so you can add another one:

SetEnv ACCESS_FILE_NAME .another-name

And get it in php using $_SERVER['ACCESS_FILE_NAME']
