<?
session_start();
if (!isset($page)) {
	session_register("page");
	$page = 0;
}
?>

I think this is what you want. This will keep the value of $page for the
remainder of the session, but will only set it to '0' on the first visit.
You can change the value of $page to whatever you want after that.
