一、下载workerman
//www.workerman.net/download

二、下载workerman/mysql

//doc3.workerman.net/640201

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 runn";
    });
};
// 运行worker
Worker::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 ...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 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 ...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, $content), false);
};
// 运行worker
Worker::runAll();
4、定时函数为类方法（类内部使用定时器）
require_once './Workerman/Autoloader.php';
use WorkermanWorker;
use WorkermanLibTimer;
class Mail{
// 注意，回调函数属性必须是public
    public function send($to, $content){
        echo "send mail ...n";
    }
    public function sendLater($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 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 ...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 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 ...n";
    }
}
$task = new Worker();
$task->onWorkerStart = function($task){
    // 10秒后发送一次邮件
    $to = 'workerman@workerman.net';
    $content = 'hello workerman';
    // 定时调用带命名空间的类的静态方法
    Timer::add(10, array('TaskMail', 'send'), array($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 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 $countn";
        // 运行10次后销毁当前定时器
        if($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 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}...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 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n";
        });
    }
};
// 运行worker
Worker::runAll();

来看一个完整的示例，shipments.php用来写定时任务

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);
    $url  = "//114.55.144.79/taobao/TradeFullinfoGetRequest.php?shop=$taobao&tid=$orderId";
    $json  = curlGet($url);
    return json_decode($json, true)['trade'];
}
Worker::runAll();
