How to remove .php extension the pro way - php

Question

I have created my first Php solution but have trouble removing the .php extension from the URL. It works in the root but not in sub-folders?
Eg www.domain.com/index.php reached from www.domain.com/index (or www.domain.com/)
Then it gets tricky.
For example. www.domain.com/en/europe/bikes/racer-bike.php will not differ from www.domain.com/en/bikes/racer-bike without ending up on www.domain.com/en/bikes/ and on index.php
My .htaccess file looks like this:
Options -MultiViews
RewriteEngine on
RewriteBase /
# Remove .php-extension from url
RewriteCond %{REQUEST_URI} ^/(.*).php$
RewriteRule ^(.*)$ %1 [L,QSA]
# Add trailing slash to url
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/|#(.*))$
RewriteRule ^(.*)$ $1/ [R=301,L]
# SSL
RewriteCond %{HTTP_HOST} ^domain.com$
RewriteRule ^(.*)$ http://www.domain.com$1 [R=301]
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^/?(.*)$ https://%{SERVER_NAME}/$1 [L,R=301,QSA]

Answer 1

I Try it and it works:
My dirs structure
/
index.php
/sub
file.php
And my htaccess like this:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^/([^\/]*)$
RewriteRule ^([^\/]*)$ $1.php [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ([A-Za-z]+)/(.*)$ [NC]
RewriteCond %{DOCUMENT_ROOT}/%1 -d
RewriteRule ^([A-Za-z]+)/(.*)$ $1/$2.php [NC,L,QSA]
Try it

You are doing it wrong ... Mostly you do not make php files for each uri (route). You should not remove php extension you should direct all uri's to index.php and use some router to define how to handle each request. or you can just use some framework to do that like laravel or symfony etc.
