You're calling a method of Database that doesn't exist, hence the
error "Call to undefined method. You define the class Database, but it
has no Open(), Query(), FetchArray() or Close() methods defined. If
you want it to inherit methods from some base class, you're going to
need to define your class doing something like:
class Database extends BaseClass {
}

what is this using() function at the top? Is that a user defined
function that does a require on a file in the path?

ps... I hope that's not your actual user/pass pasted in the code... if
so I would change it now that it has been shared with a bunch of
strangers.
