interface sees whole database

Hello, Long time listener, first time caller. I do web hosting, but am very new to php. I have a client who is using an interface that is very nice, but with one big problem for me. He can see all of the databases on the server. It is even apparent that he might have some control (edit, drop) over them too. I don't think this person would have brought it to my attention if these were his intentions, but none the less, i can not have a customer with access to all of the databases. If maybe one of you guru's are bored today, could you please look at this script www.ghostone.com/mysql and tell me if there is a quick fix. offering my first born in advance shawn
