Suppose domain is domain.name,
after a new user sign up,need to generate a new domain:user1.domain.name.
How to implement it?
BTW,is there a limit for the number of sub domains?

A:
I would simply use a wildcard to point all subdomains to a certain directory and have a front controller there that determines the used one from the URL - this is the easiest and safest solution from PHP.
EDIT Then you can obviously check whether that one should be existing (store them in a database or whatever) etc.

Can you be more specific about `determines the used one from the URL`

The domain is in `$_SERVER['HTTP_HOST']`. Not sure if there are any exceptions to this case, though. Then you can just explode the string by dots and off you go.

What you are asking for is known as Wildcard DNS record:
Basic DNS/Apache setup:
App-side logic (crappy code):

* there is no need of domain generation and there is no limit of subdomains

A:
Subdomains can be retrieved with .htaccess (you need however wildcard mentioned earlier in this thread):
RewriteEngine On
RewriteCond %{HTTP_HOST} ^user([0-9]{1,10}).domain.name$
RewriteRule ^.*$ index.php?subdomain=%1
