I have a bunch of PHP scripts inside of, say, /public_html/mydir/, and these scripts may possibly try to delete files / do other stuff to the filesystem.
I want to allow all filesystem modifications within the /public_html/mydir/ directory, but any access (or deletion) outside of the mydir directory shouild not be allowed.
How can I do this?

You either make a user that only has permission to access these directories, or you have to somehow run PHP in a sandbox like chroot
