Converting URLs

UPDATE 1:

Sorry, what I meant was this:

I currently have the following url:

http://www.companyname.com/page.php

How can I convert that to

http://www.companyname.com/group/name

and

http://www.companyname.com/group/name/

ORIGINAL QUESTION:

I currently have th开发者_高级运维e following url:

http://www.companyname.com/page.php

How can I convert that to

http://www.companyname.com/group/page

Something along these lines:

RewriteRule ^group/page/?$ page.php

or:

RewriteRule ^group/(.+)/?$ $1.php

for other pages in this style.

I assume you want the user to see /group/page, as it is prettier.

RewriteEngine On
RewriteRule ^group/(.+)$ $1.php

There is a lot of instructions on this theme.

For example

Please URL Rewrite in php
