这篇文章将为大家详细讲解有关如何在php中基于workerman实现一个定时任务，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。
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=newWorker();
//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"taskrun\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
functionsend_mail($to,$content)
{
echo"sendmail...\n";
}
$task=newWorker();
$task->onWorkerStart=function($task)
{
$to='workerman@';
$content='helloworkerman';
//10秒后执行发送邮件任务，最后一个参数传递false，表示只运行一次
Timer::add(10,'send_mail',array($to,$content),false);
};
//运行worker
Worker::runAll();
3、定时函数为类的方法require_once'./Workerman/Autoloader.php';
use\Workerman\Worker;
use\Workerman\Lib\Timer;
classMail
{
//注意，回调函数属性必须是public
publicfunctionsend($to,$content)
{
echo"sendmail...\n";
}
}
$task=newWorker();
$task->onWorkerStart=function($task)
{
//10秒后发送一次邮件
$mail=newMail();
$to='workerman@';
$content='helloworkerman';
Timer::add(10,array($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;
classMail
{
//注意，回调函数属性必须是public
publicfunctionsend($to,$content)
{
echo"sendmail...\n";
}
publicfunctionsendLater($to,$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=newWorker();
$task->onWorkerStart=function($task)
{
//10秒后发送一次邮件
$mail=newMail();
$to='workerman@';
$content='helloworkerman';
$mail->sendLater($to,$content);
};
//运行worker
Worker::runAll();
5、定时函数为类的静态方法require_once'./Workerman/Autoloader.php';
use\Workerman\Worker;
use\Workerman\Lib\Timer;
classMail
{
//注意这个是静态方法，回调函数属性也必须是public
publicstaticfunctionsend($to,$content)
{
echo"sendmail...\n";
}
}
$task=newWorker();
$task->onWorkerStart=function($task)
{
//10秒后发送一次邮件
$to='workerman@';
$content='helloworkerman';
//定时调用类的静态方法
Timer::add(10,array('Mail','send'),array($to,$content),false);
};
//运行worker
Worker::runAll();
6、定时函数为类的静态方法(带命名空间)namespaceTask;
require_once'./Workerman/Autoloader.php';
use\Workerman\Worker;
use\Workerman\Lib\Timer;
classMail
{
//注意这个是静态方法，回调函数属性也必须是public
publicstaticfunctionsend($to,$content)
{
echo"sendmail...\n";
}
}
$task=newWorker();
$task->onWorkerStart=function($task)
{
//10秒后发送一次邮件
$to='workerman@';
$content='helloworkerman';
//定时调用带命名空间的类的静态方法
Timer::add(10,array('\Task\Mail','send'),array($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=newWorker();
$task->onWorkerStart=function($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,&$count)
{
echo"Timerrun$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;
classMail
{
publicfunctionsend($to,$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:$this->count;
//运行10次后销毁当前定时器
echo"sendmail{$this->count}...\n";
if($this->count++>=10)
{
echo"Timer::del($timer_id)\n";
Timer::del($timer_id);
}
}
}
$task=newWorker();
$task->onWorkerStart=function($task)
{
$mail=newMail();
//要想$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。useWorkerman\Worker;
useWorkerman\Lib\Timer;
require_once'./Workerman/Autoloader.php';
$worker=newWorker();
$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
useWorkerman\Worker;
use\Workerman\Lib\Timer;
require_once"Workerman/Autoloader.php";
require_once"Connection.php";
$task=newWorker();
$task->onWorkerStart=function($task){
global$db,$redis;
$db=new\Workerman\MySQL\Connection('127.0.0.1','3306','root','root','test');
$redis=newRedis();
$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);
});
};
functioncurlGet($url='',$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;
}
functionnewGetOrderInfo($taobao,$orderId)
{
$taobao=urlencode($taobao);
$url="http://114.55.144.79/taobao/TradeFullinfoGetRequest.php?shop=$taobao&tid=$orderId";
$json=curlGet($url);
returnjson_decode($json,true)['trade'];
}
Worker::runAll();
