php workerman定时任务的实现代码


						一、下载workerman



http://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

    $this->count = empty($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 (!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();
