note 53970 added to function.setcookie

I am confused about something, when you want to save $_SESSION data to a cookie, don't you use session_register? or do you have to store $_SESSION['stuff'] = $variable then setcookie('$variable') ? I don't understand. someone told me session_register already stores the session into a cookie, so I am confused on that part. ---- Manual Page -- http://www.php.net/manual/en/function.setcookie.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53970 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53970&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53970&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53970&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53970&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+53970&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53970&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53970&report=yes Search -- http://master.php.net/manage/user-notes.php
