workerman是一个高性能的PHP socket 服务器框架，workerman基于PHP多进程以及libevent事件轮询库，PHP开发者只要实现一两个接口，便可以开发出自己的网络应用，例如Rpc服务、聊天室服务器、手机游戏服务器等。
workerman的目标是让PHP开发者更容易的开发出基于socket的高性能的应用服务，而不用去了解PHP socket以及PHP多进程细节。 workerman本身是一个PHP多进程服务器框架，具有PHP进程管理以及socket通信的模块，所以不依赖php-fpm、nginx或者apache等这些容器便可以独立运行
以下我们来重点来来workerman是如何实现定时任务的
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 WorkermanWorker;use WorkermanLibTimer;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”; });};// 运行workerWorker::runAll();
2、定时函数为普通函数
require_once ‘./Workerman/Autoloader.php’;use WorkermanWorker;use WorkermanLibTimer;// 普通的函数function send_mail($to, $content){ echo “send mail …”;}$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, $content), false);};// 运行workerWorker::runAll();
3、定时函数为类的方法
require_once ‘./Workerman/Autoloader.php’;use WorkermanWorker;use WorkermanLibTimer;class Mail{ // 注意，回调函数属性必须是public public function send($to, $content) { echo “send mail …”; }}$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, $content), false);};// 运行workerWorker::runAll();
4、定时函数为类方法(类内部使用定时器)
require_once ‘./Workerman/Autoloader.php’;use WorkermanWorker;use WorkermanLibTimer;class Mail{ // 注意，回调函数属性必须是public public function send($to, $content) { echo “send mail …”; } public function sendLater($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, $content);};// 运行workerWorker::runAll();
5、定时函数为类的静态方法
require_once ‘./Workerman/Autoloader.php’;use WorkermanWorker;use WorkermanLibTimer;class Mail{ // 注意这个是静态方法，回调函数属性也必须是public public static function send($to, $content) { echo “send mail …”; }}$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, $content), false);};// 运行workerWorker::runAll();
6、定时函数为类的静态方法(带命名空间)
namespace Task;require_once ‘./Workerman/Autoloader.php’;use WorkermanWorker;use WorkermanLibTimer;class Mail{ // 注意这个是静态方法，回调函数属性也必须是public public static function send($to, $content) { echo “send mail …”; }}$task = new Worker();$task->onWorkerStart = function($task){ // 10秒后发送一次邮件 $to = ‘workerman@workerman.net’; $content = ‘hello workerman’; // 定时调用带命名空间的类的静态方法 Timer::add(10, array(‘TaskMail’, ‘send’), array($to, $content), false);};// 运行workerWorker::runAll();
7、定时器中销毁当前定时器(use闭包方式传递$timer_id)
use WorkermanWorker;use WorkermanLibTimer;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 $count”; // 运行10次后销毁当前定时器 if($count++ >= 10) { echo “Timer::del($timer_id)”; Timer::del($timer_id); } });};// 运行workerWorker::runAll();
8、定时器中销毁当前定时器(参数方式传递$timer_id)
require_once ‘./Workerman/Autoloader.php’;use WorkermanWorker;use WorkermanLibTimer;class Mail{ public function send($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 $this->count = empty($this->count) ? 1 : $this->count; // 运行10次后销毁当前定时器 echo “send mail {$this->count}…”; if($this->count++ >= 10) { echo “Timer::del($timer_id)”; 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’, &$timer_id));};// 运行workerWorker::runAll();
9、只在指定进程中设置定时器
一个worker实例有4个进程，只在id编号为0的进程上设置定时器。
use WorkermanWorker;use WorkermanLibTimer;require_once ‘./Workerman/Autoloader.php’;$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”; }); }};// 运行workerWorker::runAll();
看看完整的示例
shipments.php用来写定时任务
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2018/11/29 * Time: 16:59 */use WorkermanWorker;use WorkermanLibTimer;require_once “Workerman/Autoloader.php”;require_once “Connection.php”;$task = new Worker();$task->onWorkerStart = function ($task) { global $db, $redis; $db = new WorkermanMySQLConnection(‘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 (!empty($options)) { curl_setopt_array($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();
