from google got

to remove index.php or index.html

rewritecond %{the_request} \ /(.+/)?index\.(html?|php)(\?.*)?\  [nc] rewriterule ^(.+/)?index\.(html?|php)$ ./$1 [r=301,l] 

to make end slash

rewritecond %{script_filename} !-f rewriterule [^/]$ %{request_uri}/ [r=301,l]  rewritecond %{request_uri} ^(/.*[^/])/?$ rewritecond %{document_root}%1.php -f rewriterule ^([^/]+)/?$ ./$1.php [qsa,l] 

to make /page-name/

rewriterule ^([^/]*)/$ ./index.php?page=$1  [qsa,l] 

any simple or better one?
