(要求Workerman版本>=3.3.6)

安装：

composer require react/child-process

示例：

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
$worker = new Worker('tcp://127.0.0.1:1234');
$worker->onWorkerStart = function() {
    $loop    = Worker::getEventLoop();
    $process = new React\ChildProcess\Process('echo hello');
    $process->start($loop);
    $process->on('exit', function($exitCode, $termSignal) {
        echo "cmd complete\n";
    });
    $process->stdout->on('data', function($output) {
        echo $output;
    });
    $process->stderr->on('data', function($output) {
        echo $output;
    });
};
Worker::runAll();

注意：

1、所有的异步编码必须在onXXX回调中编写

2、异步客户端需要的$loop变量请使用Worker::getEventLoop();返回值
