php workerman定时任务的实现代码

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 = '[email protected]';
  $content = 'hello workerman';
  // 10秒后执行发送邮件任务，最后一个参数传递false，表示只运行一次
  Timer::add(10, 'send_mail', array($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 = '[email protected]';
  $content = 'hello workerman';
  Timer::add(10, array($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 = '[email protected]';
  $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 = '[email protected]';
  $content = 'hello workerman';
  // 定时调用类的静态方法
  Timer::add(10, array('Mail', 'send'), array($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 = '[email protected]';
  $content = 'hello workerman';
  // 定时调用带命名空间的类的静态方法
  Timer::add(10, array('\Task\Mail', 'send'), array($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();
