父进程与子进程间如何互相调用参数

素年锦时 更新于2019-10-30

$httpserver = new Worker('websocket://0.0.0.0:1000');
$httpserver->onMessage = function($conhttp,$msg)use($connection)
{
    print_r($msg);
};
$httpserver->onWorkerStart = function($conhttp)
{
    $connection = new AsyncTcpConnection('tcp://10.10.10.200:8021');
        $connection->onMessage = function($connection,$buffer)use($conhttp)
        { 
                  //如何在此处获取到$msg的值
        };
};

首先你这也不是父子进程之间的通信，onXXX回调方法里的都是子进程逻辑。
AsyncTcpConnection（8021）啥意思？应该是AsyncTcpConnection（1000），参考代码【不过只适用于单进程模型】：

<?php
use Workerman\Worker;
use Workerman\Lib\Timer;
use Workerman\Connection\AsyncTcpConnection;
require_once dirname(__DIR__) . '/Workerman/Autoloader.php';

$worker = new Worker('text://0.0.0.0:3000');
$worker->count = 1;

$worker->onWorkerStart = function($worker) {
    $connection = new AsyncTcpConnection('text://127.0.0.1:3000');
    $connection->connect();
    $connection->onMessage = function($connection, $msg){
        pprint($msg);
    };  
}; 

$worker->onMessage = function($connection, $msg){
    foreach($connection->worker->connections as $one_connection){
        $one_connection->send($msg);
    }   
};

Worker::runAll();

对于多进程之间的通信，有很多方法：
（1）使用官方提供的GlobalData组件或者 Channle组件。
（2）使用 redis、memcache 或者 mysql 等。
（3）使用类似官方的GatewayWorker通信模型，即：注册一个全局register进程，$httpserver进程onWorkerStart时连接register进程，这样当不同进程的客户端通信时，交由register进程来转发数据。
