Question

How do I do this? There are many topics about this but I tried all of them and it did not work.

Can someone give me an elaborate and extensive answer as I have practically no experience with .htaccess?

Answer 1

From mind, so might need some tweaking

RewriteEngine on
RewriteRule ^([^.]*)/?$ index.php?p=$1 [L]

This will (internally!) send example.com/xxx to /example.com/index.php?p=xxx

So in the index.php you can do whatever you want with the $_GET['p'] as you would normally do but the user will see the site as index.example.com/xxx
