I'm having trouble with a "Fatal" PHP error . . . Can someone help me?

I'm making a web Site (http://www.planet-lybibalot.com/) and have been learning about new scripts along the way. One of the types of scripts I've been learning about is PHP. Right now, I'm TRYING to put up a Game Site to draw in costumers, and frankly, I have been having a LOT of trouble with a sertain script! The script I'm using HAD a LOT of errors, but I've been able to work through most of them. There is, however, one error that I can't figure out. The error it has been giving me is as follows:

Fatal error: Call to undefined function: adonewconnection() in /home/lybib/public_html/games/blacknova/global_funcs.php on line 225

I have figured out which Line it's talking about, but cannot figure out how to deal with it. The Line is as follows:

$db = ADONewConnection("$db_type");

If any of you can tell me how to deal with this error, please reply back to me, or E-Mail me at the following address:

Your code is calling ADONewConnection(), and the error msg is telling you that no such function exists.

Solution:
1. Create a function named ADONewConnection
2. Don't call the function.
