subdomains through php

[sysop073]

Does anybody know how to setup subdomains (so hi.mysite.com can go to mysite.com/hi or wherever else i want) through php? if not that, at least through IIS?

I think this will have to be done on the server, but I don't know IIS at all...

if you are thinking of what i am thinking of, try taking advantage of the $_SERVER['HTTP_HOST'] variable, it shows the domian and, I think, the subdomain.


list($subdomain,$domain,$extention) = explode('.',$_SERVER['HTTP_HOST']);
//$subdomain is somthing like 'pear'
//$domain is somthing like 'php'
//$extention is somthing like 'net'
