I need to direct multiple domains to a single set of (PHP) files. So I point a domain at my server, which then goes to a single index.php file. This index.php file then detects the domain accessing it and returns the appropriate content. I do not want to add domains or set-up sites manually though as this is for a content management service. So it should be a case of a user signing up and it immediately works without me having to manually do anything. The file set must also exist only once, so updates can easily be applied to everyone.

I am currently on shared hosting, but I believe I may need to move to a VPS (running Apache) to achieve this.

How do I go about doing this?

Thanks

    Unless I’m missing something about what you’re trying to do, a simple CNAME DNS record may work. Just CNAME the new domain to your existing ‘main’ domain.

    However, if you need to know what domain was requested using shared hosting this very well may not work. The catch is you would also have to setup the hosting account to accept requests from the new domain. This seems to be what you’re trying to avoid.

    If this is the case, you’ll need a static IP, and Apache setup to accept wildcard domains and pass them to your application (index.php in this case). You may not need a VPS for this, just a relatively configurable shared hosting account.

    Update: To get this working on shared hosting, check out the Apache VirtualHost directive. That’s what Apache uses to setup a (wait for it) ‘virtual’ web server (document root, logs, etc) allowing a single server to host multiple sites. Also checkout Named Based Virtual Hosting, you’ll need an account that doesn’t do virtual hosting that way.
