## 简介 ##

常规定时器：linux crontab

Swoole定时器  
swoole\_timer\_tick  
swoole\_timer\_after

## 别名 ##

tick()、after()、clear() 都拥有一个函数风格的别名

### Ws.php ###

        after()
        在指定的时间后执行函数。Swoole\Timer::after 函数是一个一次性定时器，执行完成后就会销毁。
    
        此函数与 PHP 标准库提供的 sleep 函数不同，after 是非阻塞的。而 sleep 调用后会导致当前的进程进入阻塞，将无法处理新的请求。
