Hello, just got a new website up and running. I use several PHP includes to make sitewide changes easy.

For example I have a settings.php file that just contains my doctype and my <head></head> stuff. I don't want this visible for someone to just go to my site and do ryanreese.us/settings.php (not that people *should* know it exists)..but still.

What permissions would I have to set for this to happen?

I was unable to think of the correct keywords in a google search.
