I could be wrong but I dont think its possible. I think you need to actually setup a subdomain, or go into the dns server.

I read your post, and what blogspot is doing seems to be what everyone else is doing. Maybe theyre doing some of it with php (like creating directories for the users) but Im sure theres more to it

It is easy, If your DNS is set up with a wildcard to point to your main site.

Here is a start, all you have to set is the domain var, and set this to your domain name with out the .com


<?php

$domain = "apple"; // eg: apple.com
$host = $_SERVER['HTTP_HOST'];
$vars = explode(".", $host);
if(($vars['0'] != "www") or ($vars['0'] != $domain)){
if(file_exists("/{$var['0']}/")){
header("Location: /{$var['0']}/");
}
}
echo("The Sub Domain is not a valid user, so here is the main site.");

?>
