Rewrite Engine (Messy)

Anyways.. To redirect a website, say example.co.uk to say example.co.uk/file.php

RewriteEngine on RewriteCond %{HTTP_HOST} ^example\.co\.uk$
[OR] RewriteCond %{HTTP_HOST} ^www\.example\.co\.uk$
RewriteRule ^/?$ "https\:\/\/example\.co\.uk\/file.php"
[R=301,L]

To rewrite PHP files

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)/?$ $1.php [NC,L]
RewriteCond %{THE_REQUEST} /([^.]+)\.php [NC]
RewriteRule ^ /%1 [NC,L,R]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [NC,L]

To rewrite HTML files

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)$ $1.html [NC,L]
RewriteEngine on
RewriteCond %{THE_REQUEST} /([^.]+)\.html [NC]
RewriteRule ^ /%1 [NC,L,R]
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^ %{REQUEST_URI}.html [NC,L]

To ensure access is limited and not exposed

<Files 403.shtml>
order allow,deny
allow from all
</Files>
