I have this path in localhost (localhost/ams/forms/login.php). I want to redirect for clean url (localhost/ams/forms/login/) when I type localhost/ams.

This for clear .php from url

RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule !.*\.php$ %{REQUEST_FILENAME}.php [QSA,L]

this for redirect from old file path to new file path

Redirect /olddirectory/oldfile.html http://example.com/newdirectory/newfile.html
