swoole 如何高效编写实时爬虫以及实时提醒服务（task）

1. 在提交问答前请尽可能回答以下问题：

2. 请详细描述问题的产生过程，贴出相关的代码，最好能提供一份可稳定重现的简单脚本代码。
```php
public function onTask($serv, $task_id, $from_id, $data){
       
        while (true) {
            //执行爬虫代码
            sleep(10);
            //返回任务执行的结果
            $serv->finish("$data -> OK");
        }
        
    }
```

3. 期望的结果是什么？
	还有没有其它可代替此代码的方案呢？
4. 实际运行的结果是什么？
	暂无
5. 你的版本? 贴出 `php --ri swoole` 所打印的内容

6. 你使用的机器系统环境是什么（包括内核、PHP、gcc编译器版本信息）？可以使用`uname -a`, `php -v`, `gcc -v` 命令打印
