<?php    function newChild($func_name) {      echo "enter newChild\n";      $args = func_get_args();      unset($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;      }  }    (PS:^_^不錯的php開發交流群:256271784,驗證:csl,有興趣的話可以加入進來一起討論)function on_timer() {      echo "timer called\n";  }      /**  * @param $func string, function name  * @param $timeouts int, microtimes for time delay  */  function timer($func, $timeouts){          echo "enter timer\n";      $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 exit\n";  }
