body: <p>I'm trying to put together some htaccess code that will turn <strong>example.com/filename.php</strong> into <strong>example.com/filename/</strong> (and force the slash) - I've tried varous approaches, but each hasn't worked quite right, from 500 errors on subfolders to issues with the trailing slash, etc...</p>
