这篇文章主要介绍了php workerman定时任务的实现代码,小编觉得挺不错的,现在分享给大家,也给大家做个参考,一起跟随小编过来看看吧
一、下载workerman
https://www.workerman.net/download
二、下载workerman/mysql
http://doc3.workerman.net/640201
1、定时函数为匿名函数(闭包)
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- require_once './Workerman/Autoloader.php';
- $task = new Worker();
- // 开启多少个进程运行定时任务,注意多进程并发问题
- $task->count = 1;
- $task->onWorkerStart = function($task)
- {
- // 每2.5秒执行一次
- $time_interval = 2.5;
- Timer::add($time_interval, function()
- {
- echo "task run\n";
- });
- };
- // 运行worker
- Worker::runAll();
2、定时函数为普通函数
- require_once './Workerman/Autoloader.php';
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- // 普通的函数
- function send_mail($to, $content)
- {
- echo "send mail ...\n";
- }
- $task = new Worker();
- $task->onWorkerStart = function($task)
- {
- $to = 'workerman@workerman.net';
- $content = 'hello workerman';
- // 10秒后执行发送邮件任务,最后一个参数传递false,表示只运行一次
- Timer::add(10, 'send_mail', array($to, $content), false);
- };
- // 运行worker
- Worker::runAll();
3、定时函数为类的方法
- require_once './Workerman/Autoloader.php';
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- class Mail
- {
- // 注意,回调函数属性必须是public
- public function send($to, $content)
- {
- echo "send mail ...\n";
- }
- }
- $task = new Worker();
- $task->onWorkerStart = function($task)
- {
- // 10秒后发送一次邮件
- $mail = new Mail();
- $to = 'workerman@workerman.net';
- $content = 'hello workerman';
- Timer::add(10, array($mail, 'send'), array($to, $content), false);
- };
- // 运行worker
- Worker::runAll();
4、定时函数为类方法(类内部使用定时器)
- require_once './Workerman/Autoloader.php';
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- class Mail
- {
- // 注意,回调函数属性必须是public
- public function send($to, $content)
- {
- echo "send mail ...\n";
- }
- public function sendLater($to, $content)
- {
- // 回调的方法属于当前的类,则回调数组第一个元素为$this
- Timer::add(10, array($this, 'send'), array($to, $content), false);
- }
- }
- $task = new Worker();
- $task->onWorkerStart = function($task)
- {
- // 10秒后发送一次邮件
- $mail = new Mail();
- $to = 'workerman@workerman.net';
- $content = 'hello workerman';
- $mail->sendLater($to, $content);
- };
- // 运行worker
- Worker::runAll();
5、定时函数为类的静态方法
- require_once './Workerman/Autoloader.php';
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- class Mail
- {
- // 注意这个是静态方法,回调函数属性也必须是public
- public static function send($to, $content)
- {
- echo "send mail ...\n";
- }
- }
- $task = new Worker();
- $task->onWorkerStart = function($task)
- {
- // 10秒后发送一次邮件
- $to = 'workerman@workerman.net';
- $content = 'hello workerman';
- // 定时调用类的静态方法
- Timer::add(10, array('Mail', 'send'), array($to, $content), false);
- };
- // 运行worker
- Worker::runAll();
6、定时函数为类的静态方法(带命名空间)
- namespace Task;
- require_once './Workerman/Autoloader.php';
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- class Mail
- {
- // 注意这个是静态方法,回调函数属性也必须是public
- public static function send($to, $content)
- {
- echo "send mail ...\n";
- }
- }
- $task = new Worker();
- $task->onWorkerStart = function($task)
- {
- // 10秒后发送一次邮件
- $to = 'workerman@workerman.net';
- $content = 'hello workerman';
- // 定时调用带命名空间的类的静态方法
- Timer::add(10, array('\Task\Mail', 'send'), array($to, $content), false);
- };
- // 运行worker
- Worker::runAll();
7、定时器中销毁当前定时器(use闭包方式传递$timer_id)
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- require_once './Workerman/Autoloader.php';
- $task = new Worker();
- $task->onWorkerStart = function($task)
- {
- // 计数
- $count = 1;
- // 要想$timer_id能正确传递到回调函数内部,$timer_id前面必须加地址符 &
- $timer_id = Timer::add(1, function()use(&$timer_id, &$count)
- {
- echo "Timer run $count\n";
- // 运行10次后销毁当前定时器
- if($count++ >= 10)
- {
- echo "Timer::del($timer_id)\n";
- Timer::del($timer_id);
- }
- });
- };
- // 运行worker
- Worker::runAll();
8、定时器中销毁当前定时器(参数方式传递$timer_id)
- require_once './Workerman/Autoloader.php';
- use \Workerman\Worker;
- use \Workerman\Lib\Timer;
- class Mail
- {
- public function send($to, $content, $timer_id)
- {
- // 临时给当前对象添加一个count属性,记录定时器运行次数
- $this->count = emptyempty($this->count) ? 1 : $this->count;
- // 运行10次后销毁当前定时器
- echo "send mail {$this->count}...\n";
- if($this->count++ >= 10)
- {
- echo "Timer::del($timer_id)\n";
- Timer::del($timer_id);
- }
- }
- }
- $task = new Worker();
- $task->onWorkerStart = function($task)
- {
- $mail = new Mail();
- // 要想$timer_id能正确传递到回调函数内部,$timer_id前面必须加地址符 &
- $timer_id = Timer::add(1, array($mail, 'send'), array('to', 'content', &$timer_id));
- };
- // 运行worker
- Worker::runAll();
9、只在指定进程中设置定时器
一个worker实例有4个进程,只在id编号为0的进程上设置定时器。
- use Workerman\Worker;
- use Workerman\Lib\Timer;
- require_once './Workerman/Autoloader.php';
- $worker = new Worker();
- $worker->count = 4;
- $worker->onWorkerStart = function($worker)
- {
- // 只在id编号为0的进程上设置定时器,其它1、2、3号进程不设置定时器
- if($worker->id === 0)
- {
- Timer::add(1, function(){
- echo "4个worker进程,只在0号进程设置定时器\n";
- });
- }
- };
- // 运行worker
- Worker::runAll();
示例
shipments.php用来写定时任务
- <?php
- /**
- * Created by PhpStorm.
- * User: Administrator
- * Date: 2018/11/29
- * Time: 16:59
- */
- use Workerman\Worker;
- use \Workerman\Lib\Timer;
- require_once "Workerman/Autoloader.php";
- require_once "Connection.php";
- $task = new Worker();
- $task->onWorkerStart = function ($task) {
- global $db, $redis;
- $db = new \Workerman\MySQL\Connection('127.0.0.1', '3306', 'root', 'root', 'test');
- $redis = new Redis();
- $redis->connect('127.0.0.1', 6379);
- $redis->auth("qqq123123.");
- $time_interval = 0.1;
- Timer::add($time_interval, function () {
- global $db, $redis;
- $insert['name'] = 123;
- $db->insert('shipments')->cols($insert)->query();
- // sleep(100);
- });
- };
- function curlGet($url = '', $options = [])
- {
- $ch = curl_init($url);
- curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
- curl_setopt($ch, CURLOPT_TIMEOUT, 30);
- if (!emptyempty($options)) {
- curl_setopt_array($ch, $options);
- }
- //https请求 不验证证书和host
- curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
- curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
- $data = curl_exec($ch);
- curl_close($ch);
- return $data;
- }
- function newGetOrderInfo($taobao, $orderId)
- {
- $taobao = urlencode($taobao);
- $url = "http://114.55.144.79/taobao/TradeFullinfoGetRequest.php?shop=$taobao&tid=$orderId";
- $json = curlGet($url);
- return json_decode($json, true)['trade'];
- }
- Worker::runAll();
