Re[2]: [PHP-DEV] PHP and Threads

Hi, first of all, thanks for the bugfix. it will go into phpserv 0.02 along with a sf.net account, seperate mailinglists (to not bother php-dev anymore :)) > Thanks Daniel for your excellent input.

The question should be, how you get the _processes_ to communicate to each other. Als already mentioned by Steve Meyers, you could use the signals reserved for user space: SIGUSR1 and SIGUSR2. You can send them to another process by using posix_kill: http://php.net/posix_kill posix_kill($pid, SIGUSR1); unfortunately these signals provide only limited functionality. Another approach to IPC (inter process communication) are named pipes. I suggest you to have a look at "Beej's Guide to Unix Interprocess Communication", which provides an excellent hands-on introduction on this topic: http://www.ecst.csuchico.edu/~beej/guide/ "Beej's Guide to Network Programming" ist worth reading, too :) > I can process and parse the input from the children individually but when > upon a certain command being sent by child 1, I want *all* the children to > be issued a command. you'd have to broadcast them to all child processes. I would use a child --[request]--> parent parent --> child 1 \ --> child 2 |- broadcast --> child n / ... approach. Unfortunately my knowledge on this topic is limited. Maybe there is someone more savvy on this list :) -daniel
