Creating an error page for a subdomain that doesn't exist.

Question

I've got a number of subdomains on one of my sites. When someone goes to a subdomain that doesn't exist, I want to redirect to a 404 page on my main domain.

noexist.example.com --> example.com/404.php?subdomain=noexist (or without the query string if HTTP_REFERRER can give me that info)

I'm running LAMP on a VPS with cPanel installed. I can edit the DNS Zone file for the domain via WHM.

There are a ton of tutorials on how to create a custom 404 page, no need to redirect as apache should take care of this for you.
