Not that I know of. PHP isn't designed to work like that as a web language. No idea if you're running it as a scripting system from the command line but I would assume its the same.
The only way to keep stuff somewhere to remember it is in a DB or in a file such as the session file (which CAN be access from other scripts but you need the session id).
As you're not wanting to use the disk, neither of those are particularly great ideas... so there is one more option..
You'd need another script that cyces in a loop with a listening TCP socket. It then keeps its own variables in memory like a normal script but can accept socket connections and read/write to the connected client. It's probably not the most efficient way of doing what you want but given that your disk is already frying with activity its probably the only realistic way of achieving the desired effect. Be warned though, you can't multithread PHP scripts on windows so as far as I know, you can only handle one connection at a time. On linux you can fork so you can effectively handle more clients (as I understand it). I did once find a script that claimed to do this on windows but I didn't entirely understand how it worked after several days of disecting it.
