RE: [PHP] Re: setcookie problem: Cannot add header information - headers already sent by
He IS setting cookie before sending HTML block. Note, that he is storing
the beginning of HTL block in a HEREDOC, which he prints after setting
cookie.
Somewhere, he may be printing a blank line prior to setting cookie...that
problem has bitten me more than once, so now I'm on the look-out for it in
my code.
Bob: after the page bombs-out with error message, do a view source on the
displayed web-page

I don't think you can have an empty line (even in the php) before cookies
are set

RE: [PHP] Re: setcookie problem: Cannot add header information - headers already sent by
You can't send use setcookie after headers have been sent to the browser,
you can have white space in a php block because this is not sent to the
browser. The exception is if you have output buffering enabled.
