Removing .php extension from the URL - php

Question

I have found and used this .htaccess code that will rewrite my .php URLs into i.e. .com/privacy/ - even if I remove the trailing slash, it will nicely write it;
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/$ $1.php
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]
but when I navigate to site.com/privacy.php it still displays, and doesn't force removal of the extension nor add the trailing slash.
Can someone help?

You can use this code in root .htaccess:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=302,L,NE]
RewriteCond %{THE_REQUEST} \s/+(.+?)\.php[\s?] [NC]
RewriteRule ^ /%1 [R=302,L,NE]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}\.php -f [NC]
RewriteRule ^(.+?)/?$ $1.php [L]
