htaccess- unable to remove file extension from url php - php

Question

I am trying the following rules to remove file extension from file name but the problem is it is showing that it is removed but when I login again it is not redirecting to my home page.
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase \
RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^([^/]+)/$ $1.php
Thank You

Answer 1

In your redirection just type in page name with no extension, eg. header('Location: index'); or redirect_user('index'); and use the code below in your .htaccess file. now the link on the browser will be say "localhost/index"
RewriteEngine on
RewriteRule ^([^./]{3}[^.]*)$ /index.php?page=$1 [QSA,L]

Answer 2

I think your rules are just a little bit off. You are using THE_REQUEST to redirect php extension to non php extension but you are not using a / after %1 in the rewriterule so when the next rule is read it is not matching because it will only internally redirect if there is a / in that rule. So either add a forward slash after %1 in the second rule or make the backslash optional in the last rule. I would just make it optional in last rule so it will match either way.
Try this update and see how it works.
