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
/**
* 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();
