Redirect .php URLs to URLs without extension

Remove .php extension with .htaccess

I want to make all my website URLs, myurl/webpageexamples.php, to be renamed to its non-extension version myurl/webpageexamples, if possible in .htaccess and at the same time redirect all traffic from myurl/webpageexamples.php to the new myurl/webpageexamples.

I have found several to redirect from PHP to non-PHP like:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)\.html$ /$1 [L,R=301]

What I have:

myurl/webpageexamples.php

What I want:

myurl/webpageexamples

I would like to have the SEO score transferred to new myurl/webpageexamples.
