Hide directories in URL using htaccess - php

Question

I am trying to remove the php extension as well as hiding the sub directories using .htaccess file in my domain. However, I do not have much knowledge regarding regex and I am really stuck here. Would really appreciate if someone could assist with this!
What I'm trying to achieve is:
www.example.com/index.php to www.example.com/index
www.example.com/assets/php/company.php to www.example.com/company
CURRENT .htaccess FILE
Options +FollowSymLinks -MultiViews
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^assets/php/(.*)$ /$1 [L,NC,R=301]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php [NC,L]
#To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L,NC]
</IfModule>
Currently, I could successfully remove the .php extension from the URL as well as achieving http://www.example.com/company but it displays a 404 Not Found Error. I believe I'm missing a RewriteCond line, but I do not know how to write it. Or do I require another htaccess file in /assets/php/?
Will really appreciate if someone could assist with this! Nevertheless, thanks for reading.
Cheers,
TY

You can have your rules like this in root .htaccess:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} /assets/php/([^.]+)\.php [NC]
RewriteRule ^ /%1 [L,NC,R=301]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/assets/php/$1\.php -f [NC]
RewriteRule ^([^.]+?)/?$ assets/php/$1.php [L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f [NC]
RewriteRule ^([^.]+?)/?$ $1.php [NC,L]

USe This
RewriteEngine on
RewriteBase /
#enforce www subdomain
RewriteCond %{HTTP_HOST} !^$
RewriteCond %{HTTP_HOST} ^sitename.com [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
#forward all requests, except new/admin, to the 'new' directory without the user's awareness
RewriteRule new/admin - [S=2]
RewriteRule ^$ new/ [L]
RewriteRule (.*) new/$1 [L]
