just like you said, but my particular problem arose because a notice was
issued for an undefined variable;
I didn't check correctly for it's existence.

http://www.php.net/manual/en/function.setcookie.php
And I quote, setcookie() defines a cookie to be sent along with the rest of
the header information. Cookies must be sent before any other headers are
sent (this is a restriction of cookies, not PHP).;

There is no such restriction of cookies.
I think what the manual meant to say was that cookies must be sent prior
to any output, which is the same restriction any other header has that
you wish to set with the header() function, for example.
I have forwarded this along to the documentation
