Apache mod_rewrite - prefer files over directories with pretty URLs

Question

I want to have pretty urls so http://www.domain.com/foo will return http://www.domain.com/foo.php

The issue is that there is a directory that has the same name. I have another page at http://www.domain.com/foo/bar/baz and right now my server just returns the directory listing of foo when I request http://www.domain.com/foo

Pseudocode:
If the request plus ".php" is a file
rewrite out the file instead of the directory

Actual Code:

RewriteEngine On  
RewriteBase /  
RewriteCond %{SCRIPT_FILENAME}\.php -f  
RewriteRule (.*) $1.php [NC,L]

Answer 1

MultiViews could cause this behavior. Try to disable it.

Answer 2

You need to use the whole path:

RewriteCond "%{DOCUMENT_ROOT}%{REQUEST_FILENAME}.php" -f  

REQUEST_FILENAME is just the full path inside DocumenRoot
