for example if user XXX is registered to my site and I what to associated him the sub domain http://xxx.mydomain.com/ or http://www.mydomain.com/xxx/
what is the procedure to make it ?

回答1:

You need to setup a wildcard DNS record to catch all subdomains and send them to you web server.

Then you need to setup Apache to catch all named virtual hosts and send it to a directory.

In the directory you would set htaccess to send all requests to one script which would read the sub domain from the server variables and handle it accordingly.

If you want mydomain.com/xxx, then that's just a folder. Some hosts will also take mydomain.com/xxx and automatically make xxx.mydomain.com point to it without needing any configuration on your part. Might want to check that this isn't already the case for you.

How would you create the subdomain manually?

Good. Now automate it.
