一、下載workerman

https://www.workerman.net/download

二、下載workerman/mysql

http://doc3.workerman.net/640201

1、定時(shí)函數(shù)為匿名函數(shù)(閉包)

use /Workerman/Worker;use /Workerman/Lib/Timer;require_once './Workerman/Autoloader.php';$task = new Worker();// 開啟多少個(gè)進(jìn)程運(yùn)行定時(shí)任務(wù),注意多進(jìn)程并發(fā)問(wèn)題$task->count = 1;$task->onWorkerStart = function($task){  // 每2.5秒執(zhí)行一次  $time_interval = 2.5;  Timer::add($time_interval, function()  {    echo "task run/n";  });};// 運(yùn)行workerWorker::runAll();

2、定時(shí)函數(shù)為普通函數(shù)

require_once './Workerman/Autoloader.php';use /Workerman/Worker;use /Workerman/Lib/Timer;// 普通的函數(shù)function send_mail($to, $content){  echo "send mail .../n";}$task = new Worker();$task->onWorkerStart = function($task){  $to = 'workerman@workerman.net';  $content = 'hello workerman';  // 10秒后執(zhí)行發(fā)送郵件任務(wù),最后一個(gè)參數(shù)傳遞false,表示只運(yùn)行一次  Timer::add(10, 'send_mail', array($to, $content), false);};// 運(yùn)行workerWorker::runAll();

3、定時(shí)函數(shù)為類的方法

require_once './Workerman/Autoloader.php';use /Workerman/Worker;use /Workerman/Lib/Timer;class Mail{  // 注意,回調(diào)函數(shù)屬性必須是public  public function send($to, $content)  {    echo "send mail .../n";  }}$task = new Worker();$task->onWorkerStart = function($task){  // 10秒后發(fā)送一次郵件  $mail = new Mail();  $to = 'workerman@workerman.net';  $content = 'hello workerman';  Timer::add(10, array($mail, 'send'), array($to, $content), false);};// 運(yùn)行workerWorker::runAll();

4、定時(shí)函數(shù)為類方法(類內(nèi)部使用定時(shí)器)

require_once './Workerman/Autoloader.php';use /Workerman/Worker;use /Workerman/Lib/Timer;class Mail{  // 注意,回調(diào)函數(shù)屬性必須是public  public function send($to, $content)  {    echo "send mail .../n";  }  public function sendLater($to, $content)  {    // 回調(diào)的方法屬于當(dāng)前的類,則回調(diào)數(shù)組第一個(gè)元素為$this    Timer::add(10, array($this, 'send'), array($to, $content), false);  }}$task = new Worker();$task->onWorkerStart = function($task){  // 10秒后發(fā)送一次郵件  $mail = new Mail();  $to = 'workerman@workerman.net';  $content = 'hello workerman';  $mail->sendLater($to, $content);};// 運(yùn)行workerWorker::runAll();

5、定時(shí)函數(shù)為類的靜態(tài)方法

require_once './Workerman/Autoloader.php';use /Workerman/Worker;use /Workerman/Lib/Timer;class Mail{  // 注意這個(gè)是靜態(tài)方法,回調(diào)函數(shù)屬性也必須是public  public static function send($to, $content)  {    echo "send mail .../n";  }}$task = new Worker();$task->onWorkerStart = function($task){  // 10秒后發(fā)送一次郵件  $to = 'workerman@workerman.net';  $content = 'hello workerman';  // 定時(shí)調(diào)用類的靜態(tài)方法  Timer::add(10, array('Mail', 'send'), array($to, $content), false);};// 運(yùn)行workerWorker::runAll();

6、定時(shí)函數(shù)為類的靜態(tài)方法(帶命名空間)

namespace Task;require_once './Workerman/Autoloader.php';use /Workerman/Worker;use /Workerman/Lib/Timer;class Mail{  // 注意這個(gè)是靜態(tài)方法,回調(diào)函數(shù)屬性也必須是public  public static function send($to, $content)  {    echo "send mail .../n";  }}$task = new Worker();$task->onWorkerStart = function($task){  // 10秒后發(fā)送一次郵件  $to = 'workerman@workerman.net';  $content = 'hello workerman';  // 定時(shí)調(diào)用帶命名空間的類的靜態(tài)方法  Timer::add(10, array('/Task/Mail', 'send'), array($to, $content), false);};// 運(yùn)行workerWorker::runAll();

7、定時(shí)器中銷毀當(dāng)前定時(shí)器(use閉包方式傳遞$timer_id)

use /Workerman/Worker;use /Workerman/Lib/Timer;require_once './Workerman/Autoloader.php';$task = new Worker();$task->onWorkerStart = function($task){  // 計(jì)數(shù)  $count = 1;  // 要想$timer_id能正確傳遞到回調(diào)函數(shù)內(nèi)部,$timer_id前面必須加地址符 &  $timer_id = Timer::add(1, function()use(&$timer_id, &$count)  {    echo "Timer run $count/n";    // 運(yùn)行10次后銷毀當(dāng)前定時(shí)器    if($count++ >= 10)    {      echo "Timer::del($timer_id)/n";      Timer::del($timer_id);    }  });};// 運(yùn)行workerWorker::runAll();

8、定時(shí)器中銷毀當(dāng)前定時(shí)器(參數(shù)方式傳遞$timer_id)

require_once './Workerman/Autoloader.php';use /Workerman/Worker;use /Workerman/Lib/Timer;class Mail{  public function send($to, $content, $timer_id)  {    // 臨時(shí)給當(dāng)前對(duì)象添加一個(gè)count屬性,記錄定時(shí)器運(yùn)行次數(shù)    $this->count = empty($this->count) ? 1 : $this->count;    // 運(yùn)行10次后銷毀當(dāng)前定時(shí)器    echo "send mail {$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能正確傳遞到回調(diào)函數(shù)內(nèi)部,$timer_id前面必須加地址符 &  $timer_id = Timer::add(1, array($mail, 'send'), array('to', 'content', &$timer_id));};// 運(yùn)行workerWorker::runAll();

9、只在指定進(jìn)程中設(shè)置定時(shí)器

一個(gè)worker實(shí)例有4個(gè)進(jìn)程,只在id編號(hào)為0的進(jìn)程上設(shè)置定時(shí)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編號(hào)為0的進(jìn)程上設(shè)置定時(shí)器,其它1、2、3號(hào)進(jìn)程不設(shè)置定時(shí)器  if($worker->id === 0)  {    Timer::add(1, function(){      echo "4個(gè)worker進(jìn)程,只在0號(hào)進(jìn)程設(shè)置定時(shí)器/n";    });  }};// 運(yùn)行workerWorker::runAll();

示例

shipments.php用來(lái)寫定時(shí)任務(wù)

<?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 (!empty($options)) {    curl_setopt_array($ch, $options);  }  //https請(qǐng)求 不驗(yàn)證證書和host  curl_setopt($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();
