PHP:与workerman结合实现定时任务

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

二、下载workerman/mysql

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(){
 e ch o "4个worker进程,只在0号进程设置定时器\n";
 });
 }
};
// 运行worker
Worker::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 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 = "";
 $json = curlGet($url);
 return json_decode($json, true)['trade'];
}
Worker::runAll();
