Regarding PHP Sessions and Cookies --MelvinG?, Fri, 10 Feb 2012 08:36:41 +0100 reply

If you are trying to use PHP sessions or doing other
things that use cookies, and it's not working for you,
here is why. PHP wants the SessionID (and other cookies)
to be in the superglobal $_COOKIE[] but AbelCam puts
cookies in !$_ENV["COOKIES"]. PHP does not understand.

To solve the problem, put the following code at the
beginning of each of your PHP pages. It examines
$_ENV["COOKIES"] and loads all the cookies it finds
into $_COOKIE[] in a way that PHP can understand.

foreach (explode(";", $_ENV["COOKIES"]) as $cookie)
{
    list($key, $val) = explode("=", $cookie);
    $_COOKIE[trim($key)] = trim($val);
}
