the problem is I don't have access to the web server logs or configuration

so it seems that your "evil user" has more access than you do. You are only escaping .. s/\.\./\\\.\\\./g; so if I supply /etc/passwd as my input, how does your script handle it?

You probably should split the path into its components, and then decide from there what the file is.

He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.
