htaccess delete and ban all extensions and add / to the end of the URL

Question

I am making a small cms in php. Through htaccess I would like to delete and block all extensions (.php .html. Htm etc.) and add a / at the end of the url. ex. www.miosito/ article-name/

Options -Indexes
DirectoryIndex home.php
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ core.php

this is my current htaccess. Sorry for my bad English and thank you very much in advance
