*shrugs*. I was hoping that PHP's define() would work sort of something
along the lines of what the C preprocessor's #define does, so, while I
knew that, I didn't get the results that I'd quite expected. However,
see below...

A slight adaptation to that made it work *perfectly*. I hadn't yet run
into eval(); (at least, before today). Thanks for the pointer! The way
I worked eval(); worked great, I just needed to know what it was that I
could do:

$dbClass = DATABASE_CLASS;
eval("\$db = new ${dbClass}(DATABASE_USER, DATABASE_PASS, DATABASE_NAME);");

(It's wrapped due to the e-mail client; not so in the actual code).

Thanks!
Mike
