php cross script data questions

[PHPForever]

I want to know if there is a way to share data with multiple PHP scripts without using sessions or files?

I'm trying to create a global table (in memory) that any PHP script can modify and lookup. To do that, I obviously need a script that is constantly running. Now I though I can use a singleton class to achieve what I want but to my surprise a singleton class is only "singleton" within the same script/file. That is, if I get a singleton instance (by calling "Server:instance();") in another script, it isn't the instance in the first script - it is a totaly new object. Is that normal?
Here is the singleton class I'm using:

<?php
class Server
{

  public static $instance= false;
  public static $table= array();

  private function __construct()
  {
  }

  public static function instance()
  {
    if(!Server::$instance)
    {
      Server::$instance = new Server();
    }
    return Server::$instance;
  }

  public static function s_print()
  {
    print_r(Server::$table);
  }

  public static function s_add()
  {
    Server::$table[]= rand(1, 100);
  }
}
?>

Is there a way to use superglobals to share data with multiple PHP scripts?

I will hesitate to say that there are no other ways to share info between scripts, but sessions and files/databases are the preferred and intended methods.
