PHP 中实现Timer功能使用pcntl和libevent
[php]
<?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：^_^不错的php开发交流群：256271784，验证：csl，有兴趣的话可以加入进来一起讨论）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"; }
