workerman定时任务(workerman定时器)
一、-workerman
https://workerman-/download
二、-workerman/mysql
http://doc3.workerman-/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-';
$content = 'hello workerman';
// 10秒后执行发送邮件任务,最后一个参数传递false,表示只运行一次 Timer::add(10, 'send_mail', array($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-';
$content = 'hello workerman';
Timer::add(10, array($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-';
$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-';
$content = 'hello workerman';
// 定时调用类的静态方法 Timer::add(10, array('Mail', 'send'), array($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-';
$content = 'hello workerman';
// 定时调用带命名空间的类的静态方法 Timer::add(10, array('\Task\Mail', 'send'), array($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();
来看一个完整的示例,shipments.php用来写定时任务
