PHP 中实现Timer功能使用pcntl和libevent
- 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:cxy,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";
- }
