這篇文章主要介紹了php workerman定時任務的實現代碼，小編覺得挺不錯的，現在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧
一、下載workerman
https://www.workerman.net/download
二、下載workerman/mysql
http://doc3.workerman.net/640201
1、定時函數爲匿名函數（閉包）
use \Workerman\Worker;
use \Workerman\Lib\Timer;
require_once './Workerman/Autoloader.php';
$task = new Worker();
// 開啓多少個進程運行定時任務，注意多進程併發問題
$task->count = 1;
$task->onWorkerStart = function($task)
{
// 每2.5秒執行一次
$time_interval = 2.5;
Timer::add($time_interval, function()
{
echo "task run\n";
});
};
// 運行worker
Worker::runAll();
2、定時函數爲普通函數
require_once './Workerman/Autoloader.php';
use \Workerman\Worker;
use \Workerman\Lib\Timer;
// 普通的函數
function send_mail($to, $content)
{
echo "send mail ...\n";
}
$task = new Worker();
$task->onWorkerStart = function($task)
{
$to = '[email protected]';
$content = 'hello workerman';
// 10秒後執行發送郵件任務，最後一個參數傳遞false，表示只運行一次
Timer::add(10, 'send_mail', array($to, $content), false);
};
// 運行worker
Worker::runAll();
3、定時函數爲類的方法
require_once './Workerman/Autoloader.php';
use \Workerman\Worker;
use \Workerman\Lib\Timer;
class Mail
{
// 注意，回調函數屬性必須是public
public function send($to, $content)
{
echo "send mail ...\n";
}
}
$task = new Worker();
$task->onWorkerStart = function($task)
{
// 10秒後發送一次郵件
$mail = new Mail();
$to = '[email protected]';
$content = 'hello workerman';
Timer::add(10, array($mail, 'send'), array($to, $content), false);
};
// 運行worker
Worker::runAll();
4、定時函數爲類方法（類內部使用定時器）
require_once './Workerman/Autoloader.php';
use \Workerman\Worker;
use \Workerman\Lib\Timer;
class Mail
{
// 注意，回調函數屬性必須是public
public function send($to, $content)
{
echo "send mail ...\n";
}
public function sendLater($to, $content)
{
// 回調的方法屬於當前的類，則回調數組第一個元素爲$this
Timer::add(10, array($this, 'send'), array($to, $content), false);
}
}
$task = new Worker();
$task->onWorkerStart = function($task)
{
// 10秒後發送一次郵件
$mail = new Mail();
$to = '[email protected]';
$content = 'hello workerman';
$mail->sendLater($to, $content);
};
// 運行worker
Worker::runAll();
5、定時函數爲類的靜態方法
require_once './Workerman/Autoloader.php';
use \Workerman\Worker;
use \Workerman\Lib\Timer;
class Mail
{
// 注意這個是靜態方法，回調函數屬性也必須是public
public static function send($to, $content)
{
echo "send mail ...\n";
}
}
$task = new Worker();
$task->onWorkerStart = function($task)
{
// 10秒後發送一次郵件
$to = '[email protected]';
$content = 'hello workerman';
// 定時調用類的靜態方法
Timer::add(10, array('Mail', 'send'), array($to, $content), false);
};
// 運行worker
Worker::runAll();
6、定時函數爲類的靜態方法(帶命名空間)
namespace Task;
require_once './Workerman/Autoloader.php';
use \Workerman\Worker;
use \Workerman\Lib\Timer;
class Mail
{
// 注意這個是靜態方法，回調函數屬性也必須是public
public static function send($to, $content)
{
echo "send mail ...\n";
}
}
$task = new Worker();
$task->onWorkerStart = function($task)
{
// 10秒後發送一次郵件
$to = '[email protected]';
$content = 'hello workerman';
// 定時調用帶命名空間的類的靜態方法
Timer::add(10, array('\Task\Mail', 'send'), array($to, $content), false);
};
// 運行worker
Worker::runAll();
7、定時器中銷燬當前定時器（use閉包方式傳遞$timer_id）
use \Workerman\Worker;
use \Workerman\Lib\Timer;
require_once './Workerman/Autoloader.php';
$task = new Worker();
$task->onWorkerStart = function($task)
{
// 計數
$count = 1;
// 要想$timer_id能正確傳遞到回調函數內部，$timer_id前面必須加地址符 &
$timer_id = Timer::add(1, function()use(&$timer_id, &$count)
{
echo "Timer run $count\n";
// 運行10次後銷燬當前定時器
if($count++ >= 10)
{
echo "Timer::del($timer_id)\n";
Timer::del($timer_id);
}
});
};
// 運行worker
Worker::runAll();
8、定時器中銷燬當前定時器（參數方式傳遞$timer_id）
require_once './Workerman/Autoloader.php';
use \Workerman\Worker;
use \Workerman\Lib\Timer;
class Mail
{
public function send($to, $content, $timer_id)
{
// 臨時給當前對象添加一個count屬性，記錄定時器運行次數
$this->count = empty($this->count) ? 1 : $this->count;
// 運行10次後銷燬當前定時器
echo "send mail {$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能正確傳遞到回調函數內部，$timer_id前面必須加地址符 &
$timer_id = Timer::add(1, array($mail, 'send'), array('to', 'content', &$timer_id));
};
// 運行worker
Worker::runAll();
9、只在指定進程中設置定時器
一個worker實例有4個進程，只在id編號爲0的進程上設置定時器。
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編號爲0的進程上設置定時器，其它1、2、3號進程不設置定時器
if($worker->id === 0)
{
Timer::add(1, function(){
echo "4個worker進程，只在0號進程設置定時器\n";
});
}
};
// 運行worker
Worker::runAll();
示例
shipments.php用來寫定時任務
<?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, $options);
}
//https請求 不驗證證書和host
curl_setopt($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();
