Is this possible (DNS)??

[Anon]

My website is hosted with a company who have setup their DNS records so that any URL containing my domain will goto my webiste. I would like to setup sub-domains, but because of this setup, I have yet to find a way to do this.

Is it possible to create a php file which will look at the URL typed in by the user and then load the correct file.

For example, if the user typed in:

http://support.my-domain.org - the php file would look at it and see that it should load the file from

www.my-domain.org/support/index.html

I assume it would be a simple case of if..then..else. What I am struggling with is the layout of the code.

Many thanks to anyone who can help.

What you want is not possible using php. Subdomains must be set on the nameserver records so that the name can be resolved to an IP address, and then set by the web server to point to the correct directory.

You will have to ask your ISP to set the DNS to resolve your various subdomains (or control the DNS records yourself using the free services of hammernode (hn.org)) and then ask the server admin to add the subdomain to the httpd.conf file so that the webserver can resolve it to the correct directory.
