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 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();

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 WorkermanWorker;  use WorkermanLibTimer;    require_once "Workerman/Autoloader.php";      require_once "Connection.php";    $task = new Worker();    $task->onWorkerStart = function ($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);    $url  = "http://114.55.144.79/taobao/TradeFullinfoGetRequest.php?shop=$taobao&tid=$orderId";    $json  = curlGet($url);    return json_decode($json, true)['trade'];  }    Worker::runAll();
