htaccess Rewrite (remove php extension) - php

Question

today I have a problem with my .htaccess file. On my server I have several folders, each of folders is separately website example below:
Server structure (global folder)
- my_portfolio
- website_two
- my_website
- example
In "example" folder I have that .htaccess file:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*?)/?$ /$1.php [L]
#To remove www header
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [L,R=301]
RewriteRule working good when I open my website address is without "www" and .php extensions is invisible, but when I click on a link to other website in menu I get something like this:
www.example.com/example/contact.
Address to my website is www.example.com and everything for this website is inside example folder on a server. I dont know where or what I wrote wrong. Always when I try to go on to another webside rewrite engine give me a link without .php extension but add to folder name before link.
This is good example:
www.example.com/contact.php - normal link without htaccess
example.com/example(folder name where is a website)/contact - now
example.com/contact - should be

Reorder your rules and keep redirect rules before internal routing rules:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
#To remove www header
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [L,R=301,NE]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L,NE]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*?)/?$ $1.php [L]
Also test this from a new browser to avoid old 301 cache.
