You could get the number of messages in # a queue and handle any or all of them asynchronously. # Get the number of children you want to be born by running this # script once. $children = 5; # likely a function call here. for ($i=1; $i<=$children; $i++) { $pid = pcntl_fork(); if ($pid == -1) { die("could not fork\n"); } else if ($pid) { # If we are the parent, we did our job of giving birth, # now lets finish our job and die! exit(0); } else { # Since we are the child, fork so that init will become our parent. Init # is good at wait()ing on children - ie: reaping. $cpid = pcntl_fork(); if ($cpid == -1) { die("could not fork in child process\n"); } if (!$cpid) { # We have now forked off from our parent and also are not waiting on any # other children to process, however other children are running # simutaniously to us. Make sure the code you write here is safe to run # in this environment of multiprocessing - ie: proper locking, etc. # Write the custom code here that you want to multiprocess. # ADD CODE HERE TO MULTIPROCESS print "we are child number $i\n"; # Don't forget to exit after the child processing is done. Certainly # change this exit code if you need to however. exit(0); } } } ?> ---- Manual Page -- http://www.php.net/manual/en/ref.pcntl.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+36603 Delete -- http://master.php.net/manage/user-notes.php?action=delete+36603&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+36603&report=yes Search -- http://master.php.net/manage/user-notes.php
