htaccess Redirect sub directories except index.php

Question

I have a htaccess file in www.mydomain.com/dir.

I want to redirect requests from www.mydomain.com/dir/* to www.mydomain.com/dir except www.mydomain.com/dir/index.php

I tried this:

RewriteEngine on
RewriteCond DOCUMENT_ROOT/ !-f
RewriteRule ^/*$ index.php

What am I doing wrong?

Answer 1

This should probably work:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /dir/

RewriteRule (?!^index\.php$)^.+$ index.php [L,NC]

Answer 2

That works almost!

www.mydomain.com/dir/.htaccess:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /dir/

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (?!^index\.php$)^.+$ index.php [L,NC]

But when I access any file or sub directory in dir I get 404. The index.php is located in dir and any request to file or sub directory in dir should be redirected to dir/index.php .
