导读：?php function newChild($func_name) { echo enter newChildn; $args = func_get_args(); unset($args[0]); $pid = pcntl_fork(); if ($pid == 0) { function_exists($func_name) and exit(call_user_func_array($func_name, $args)) or exit(-1); } else if

　　<?php

　　function newChild($func_name) { echo "enter newChildn"; $args = func_get_args(); unset($args[0]); $pid = pcntl_fork(); if ($pid == 0) { function_exists($func_name) and exit(call_user_func_array($func_name, $args)) or exit(-1); } else if($pid == -1) { echo "Couldn't create child process"; } else { return $pid; }}function on_timer() { echo "timer calledn";}/** * @param $func string, function name * @param $timeouts int, microtimes for time delay */

function timer($func, $timeouts){ echo "enter timern"; $base = event_base_new(); $event = event_new(); event_set($event, 0, EV_TIMEOUT, $func); event_base_set($event, $base); event_add($event, $timeouts); event_base_loop($base);}$pid = newChild("timer", "on_timer", 5000000);if ($pid > 0) { echo "master process exitn";}
