So you want "else if (session_id() != “”) { if (array_key_exists($sVarName, $_SESSION) == TRUE) $temp = $_SESSION[$sVarName]; }" in place of the simpler code.

That's a typo, that I just fixed, from when I came back and added those lines. I don't think you need to check for a session. If there's not an active session than the isset() will catch that the variable isn't set. Of course I may be wrong. What error would come up in case a session wasn't started?

Line 28, instead of looking in $_COOKIE, attempts to call a function $_SESSION. (And $_SESSION is, of course, actually an array rather than a function.) And no check is made as to whether there is a session, which could result in a failure at line 22. There are a few things wrong with this code.
