The value of $_COOKIE is determined by the content of cookies received in the user agent's request.



If you set a cookie (ie send it to the browser), it won't be sent back until the next request and so the data won't be present in $_COOKIE.

Take note that in IE when it's really weird that when you do something like this:



<?php



// import config/constants



session_set_cookie_params((time()+$_SITE['session_length']));

session_start();

$sess = session_name();

setcookie($sess, $_COOKIE[$sess], time() + $_SITE['session_length']);



// .. rest of the code



?>



It fails. the session cookie is not stored totally.



Instead, doing this would work:



<?php



// import config/constants



session_set_cookie_params((time()+$_SITE['session_length']));

session_start();

$sess = session_name();

setcookie($sess, session_id(), time() + $_SITE['session_length']);



// .. rest of the code



?>
