I am trying to figure out how to take a domain extension from www.domain.com/page.php to be www.domain.com/page/ so it drops the .php at the end of the file extension.
ok, the best way is, make your site in wordpress or any other popular CMS, they will look after such simple and user friendly extensions. little complex way is using .htaccess files and over write extensions properly, that is tricky so if you are new or non programmer, don't try this.
