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();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();以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持网页设计。
