MMO data push method with Flash CS3

I"m creating an MMO in Flash CS3. It seems like a push method for the data (in which clients connect to a script and the script notifies each client when theres a change) would be the most efficient. Does anyone know of the best way to do this?

Any other suggestions, tips, or ideas about how to do this efficiently are definitely welcome.

Do you mean a server?

Well obviously I’ll have to use a server of some sort and I’ll most likely be using PHP and MySQL. I was wondering if anyone had any specific ideas on how I should go about streaming the data.

You’d probably have to use socket communication if you wanted an MMO. Have a look round the forums for Flash sockets tutorials
