how to hide php extension in url using .htaccess

Try my version:

# Run Php without filename extension
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php

# Return 404 if original request is .php
RewriteCond %{THE_REQUEST} "^[^ ]* .*?\.php[? ].*$"
RewriteRule .* - [L,R=404]

You can use the following.

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

Basically this says if the File in the URL can’t be found on the server then in the backend load it again using .php. This will basically make the server take a /file request and because there is no /file on the server it will load /file.php instead. The user wont see the switch over but can still load both ways.
