How to remove the .php extension?

Question

htaccess

It is impossible to remove the extension in any way.

RewriteEngine On
RewriteRule ^(([^/]+/)*[^.]+)$ /$1.php [L]

Error 404 - The requested URL /works/.php was not found on this server.
And even more desirable, you can suggest to remove the cloned pages. To be only without the extension.
Thanks in advance.
