But if you do want to hide them further for SE's you could always include the php files from a directory in which you keep the spiders away with your robots.txt file.
And my preferred method is to include them from a system directory known by the webserver but unaccessable from the Internet. This hides them for most people as well.
And if you're even more paranoid, say you don't trust security policy and other users on the same webserver for instance, you could even encrypt your php files. This requires some webserver add-ons though...
