I have referred other related question but they are not clear to me. Please explain me: How can I make subdomain in PHP?
Example :
http://www.domainn
my way:
you will have to create a wildcard subdomain and point it you your domain.
http://www.easymodrewrite.com/example-subdomains
Then you can parse $_SERVER['HTTP_HOST'] for querying out the user name .
if you are under hosting plane, you can probably create it from the GUI.
Else, you need to via the APACHE panel and configure the DNS.
