workerman的Timer定时器类的定时器注意事项-定时器id可能重复

发布时间：2021-12-05 00:16:24编辑：雪饮阅读（）

 不同进程间的定时器id可能会重复，但是同一个进程内产生的定时器id不会重复

实例：
<?php
use Workerman\Worker;
use Workerman\lib\Timer;
require_once __DIR__ . '/vendor/autoload.php';
 
$worker = new Worker();
// 5个进程
$worker->count = 5;
$worker->onWorkerStart = function(Worker $worker) {
    // 5个进程，每个进程都有一个这样的定时器
    $timer_id=Timer::add(1, function() use($worker,&$timer_id){
        echo "hi 进程id:".$worker->id.",定时器id:".$timer_id." time:".date("H:i:s",time())."\r\n";
    });
 
 
    $timer_id2=Timer::add(1, function() use($worker,&$timer_id2){
        echo "hi 进程id:".$worker->id.",定时器id:".$timer_id2." time:".date("H:i:s",time())."\r\n";
    });
 
};
Worker::runAll();
 
// 运行worker
Worker::runAll();
?>
实例运行：
[root@izj6c2jeancylo0ppo4vz5z workerman]# php test.php start
Workerman[test.php] start in DEBUG mode

可以看到有进程id不同情况下定时器id相同的情况。
 
 
 
同一进程内不断创建新的定时器，定时器的id是不会重复的：
<?php
use Workerman\Worker;
use Workerman\lib\Timer;
require_once __DIR__ . '/vendor/autoload.php';
 
$worker = new Worker();
//1个进程
$worker->count = 1;
$worker->onWorkerStart = function(Worker $worker) {
    $timers=[];
    for($i=0;$i<5;$i++){
        $timer_id=Timer::add(1, function() use($worker,$i,&$timers){
            $timer_id=$timers[$i];
           // echo "hi 进程id:".$worker->id.",定时器id:".$timer_id." time:".date("H:i:s",time())."\r\n";
        });
        $timers[$i]=$timer_id;
        echo "\r\n";
        echo "进程id:".$worker->id.",定时器id:".$timer_id;
        echo "\r\n";
    }
};
Worker::runAll();
 
// 运行worker
Worker::runAll();
?>
