how hide extension of my php files

I`m trying to hide my php files extension in my hosted server.i add following code segment in .htaccess file.

RewriteEngine on 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME}.html -f 
RewriteRule ^(.*)$ $1.html

RewriteEngine on 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME}.php -f 
RewriteRule ^(.*)$ $1.php

but when i try, it is not working. also i tried to do the same thing in my localhost.it is also not working properly.

so do i have to make any other changes to work on it?

Answer

Use

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)$ $1.php [NC,L]
