SERVER_SOCKET is ok. But the package should contain any code for handling many server-sockets simultaneously. Each accept call returns a new socket - one per client-connection. There are some ways to handle simultaneous connections: - forking - threading - select() the first two are a bit problematic implementing with PHP, so the only way is to use the select() syscall (=socket_select()). The select() syscalls returns when one of the given descriptors (sockets) is ready for reading, writing or an exception occured. I attached a small prototype, wich demonstrates such implementation, bye, -- ------------------------------- ------------------------------------- Michael Bretterklieber - Michael.Bretterklieber@jawa.at JAWA Management Software GmbH - http://www.jawa.at Liebenauer Hauptstr. 200 -------------- privat --------------- A-8041 GRAZ GSM: ++43-(0)676-93 96 698 Tel: ++43-(0)316-403274-12 E-mail: michael@bretterklieber.com Fax: ++43-(0)316-403274-10 http://www.bretterklieber.com ------------------------------- ------------------------------------- "...the number of UNIX installations has grown to 10, with more expected..." - Dennis Ritchie and Ken Thompson, June 1972
