Okay, that makes a little sense, but isn't there some sort of collection
that will do the same thing (coming from vb).

I've really only used them once, but they were handy for that situation.
I had a column in a mysql table that was a set column of user
privileges, and I wanted to register every value in the set as a session
variable.
<horridcode>
for($i = 0; $i < sizeof($privs); $i++) {
$$privs[$i] = 1;
session_register($privs[$i]);
}
</horridcode>
