This is my current .htaccess

Options +FollowSymLinks
DirectoryIndex index.php

RewriteEngine On
RewriteBase /product/

RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^(.+)\.php$ ./$1/ [R=301,L]

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule [^/]$ %{REQUEST_URI}/ [R=301,L]

RewriteRule ^contact/?$ ./contact.php [QSA,L]

Everything is working fine now..

• /product/contact return to /product/contact/
• /product/contact.php return to /product/contact/

Question..

• How to make all my .php will be /contact/ /help/ /faq/
• Now I should to add contact.php help.php faq.php to the htaccess
• I tried to add RewriteRule ^(.*)/$ $1.php [QSA,L] but it will be return loop.

Let me know how to fix it ;)
