1. You can either make sure that setcookie() is the first thing you call in your script - which is often just not a possibility.
2. Or, You can use the ob_start() and ob_end_flush() functions.

ob_start() and ob_end_flush() will buffer the content on a page until after the setcookie() variable has been created.
