Database Check

[Mythotical]

Ok I've scrapped the possibly of inserting info upon registration to multiple servers and such.

Now what I want to do is how do I connect to another DB and check it against the master DB for same user accounts, if 1 exists on master DB then it will insert a copy to the secondary DB on a different server. Right now if I can get this to work on the same server, that will do. Basically this will just be a script that runs on the page load or a cron job.

If anyone can give me a suggestion or at least a snippet of code to help me get started, I would very much appreciate it.

Thanks
