When you are working with sessions, provided you start your program with session_id(), you
can then do anything you like with session variables at any point in your program. In my
original question I asked if there was a cookie equivalent.
Someone said there was, but the above is simply demonstrating that their suggested
solution doesn't work. It appears there is no solution, but that the workaround is to turn
on output buffering, at least until you finish setting cookies, so that you can be certain
that no output is generated before this point.
