Cookies Must Be Set Before Page Output !!! Since cookies are sent by the script to the browser in the HTTP headers, before your page is sent, they must be set before you even send a single line of HTML or any other page output. The moment you send any sort of output, you are signalling the end of the HTTP headers. When that happens, you can no longer set any cookie. If you try, the setcookie() function will return FALSE, and the cookie will not be sent.
