mysql_connect to remote server

Cannot work out the replacement for localhost

[whats up skip]

I am trying to use php on one web site, but pulling the data out of data base on another server. I don't understand what the replacement should be for "localhost" in the connection string should be.

Any ideas?

Replace "localhost" with the hostname (e.g. dbhost.domain.com), or preferbly the IP address, of the external database machine.

Thanks, this put me in the right direction.
