Found a suggestion that mentioned changing the included file to .txt,
which should read it in as raw PHP. I tried that. The problem is that
the file being called for inclusion itself calls another file on the
same server as itself. This file it calls is the database connection
info. By including the file on a seperate server, the include file can
no longer access the needed database connection.
