Yes. Write a daemon which listens on a socket and manages the communications it gets from the satellite scripts and works the database for them... The scripts send off data, and process replies. They don't do the heavy work... -Original Message- From: David Buerer [mailto:[EMAIL PROTECTED]] Sent: Monday, July 22, 2002 2:30 PM To: '[EMAIL PROTECTED]' Subject: RE: [PHP] Windows NT Server, FORK, SOCKETS, and seperate processes How to I inovoke a new Thread from the middle of a PHP script? -Original Message- From: Paul Maine [mailto:[EMAIL PROTECTED]] Sent: Monday, July 22, 2002 10:08 AM To: David Buerer; [EMAIL PROTECTED] Subject: RE: [PHP] Windows NT Server, FORK, SOCKETS, and seperate processes You can use threads with NT to accomplish what you are asking. -Original Message- From: David Buerer [mailto:[EMAIL PROTECTED]] Sent: Monday, July 22, 2002 11:29 AM To: '[EMAIL PROTECTED]' Subject: [PHP] Windows NT Server, FORK, SOCKETS, and seperate processes I've got effectivly a glorified chat server which upon the arrival of a message thorugh a socket connection goes off and runs a bunch of database processed.

RE: [PHP] Windows NT Server, FORK, SOCKETS, and seperate processes
Yes, that's exactly what I want to do. But HOW do I do it?
i.e. I'm sitting in my accept connectinos loop in the chat daemon
While(true)
{
//waitforenwconnection
$new_connection_id=socket_accept();
//got a new connection, go process it
go_do_this_in_a_new_thread($new_connection_id);
}
What do I put in place of go_do_this_in_a_new_thread()
