PHP: How to run readdir() as root

Question

I am trying to make a lightweight frontend for my fileserver. I use PHP to display all the files, but readdir() is executed as the http user, because apache is started as this user.

This is a problem, because I want to view my files. 文件。 Therefore, readdir() has to be run as root, but I don't know how to do that. Can you guys help me?

Answer 1

This cannot be done. You can't run a single function as another user unless you started out as that user and then are shifting back to them temporarily.
