setcookie from php.net states the following:
setcookie() defines a cookie to be sent along with the rest of the HTTP
headers. Like other headers, cookies must be sent before any output from
your script (this is a protocol restriction). This requires that you place
calls to this function prior to any output, including <html> and <head>
tags as well as any whitespace
call setcookie before you output ANY THING, even error
hope that helps.
