数据共享组件-workerman

多进程之间是不能跨进程互相操作对方空间的变量的，可以考虑使用官方的 globalData组件 或者 redis组件来实现

composer require workerman/globaldata

###1 先开启服务端
    <?php
    require 'vendor/autoload.php'; //自动加载
    use Workerman\Worker;
    
    $global_worker  = new GlobalData\Server('127.0.0.1', 2100);//创建本地数据共享
    Worker::runAll();
    
    ?>

###2 在进程之间 调用
 可以在运行各种进程之前 初始化内容
 
    $worker = new Worker("tcp://0.0.0.0:18900");
    $worker->name = 'testWorker';
    $worker->count = 8;
    
    $global = new GlobalData\Client('127.0.0.1:2100');
    $global->count = 0; //链接人数
    $global->data = [];//具体数据
    
    **
    $worker->onWorkerStart
    $worker->onConnect

如何使用：

$worker->onConnect = function($connection) use($worker)
    {
         global $global;
         $global = new \GlobalData\Client('127.0.0.1:2100');  
         $global->increment('count');   //增加
         $odata=$newdata= $global->data;  
         $newdata[$worker->id][$connection->id]=$connection->getRemoteIp();
         $global->cas('data', $odata, $newdata); //替换   老数据  新数据 （同时并发 数据丢失）

echo '当前人数:'.$global->count."\n";
         var_dump($global->data);
         echo "\n";
        echo "new connection from  worker:".$worker->id.' conn:' . $connection->id.' ip:'. $connection->getRemoteIp() . "\n";
        file_put_contents('onConnect.txt',"new connection from  worker:".$worker->id.'conn:' . $connection->id.' ip:'. $connection->getRemoteIp()."\r\n",FILE_APPEND);
    };
