php reactive socket

php socket 第三方库 composer require react/socket

该库针对 socket / 流 做事件监听（应该是epoll ）主线程做事件循环 （reactive）所以该reactive 框架貌似只能在 linux下使用

server

<?php

require '../vendor/autoload.php';

echo "enter script\n";

$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server('127.0.0.1:8080', $loop);

$socket->on('connection', function (React\Socket\ConnectionInterface $connection) {
    echo "" . $connection->getRemoteAddress() . "client connected\n";
    $connection->write("Hello " . $connection->getRemoteAddress() . "!\n");
    $connection->write("Welcome to this amazing server!\n");
    $connection->write("Here's a tip: don't say anything.\n");

    $connection->on('data', function ($data) use ($connection) {
        echo "" . $data . "\n";
        //$connection->close();
    });
});

echo "server started at 8080\n";

$loop->run();

其中$loop 就是事件循环对象

client

<?php

require '../vendor/autoload.php';


$loop = React\EventLoop\Factory::create();
$connector = new React\Socket\Connector($loop);

$connector->connect('127.0.0.1:8080')->then(function (React\Socket\ConnectionInterface $connection) use ($loop) {
    echo "client connected\n";
    $connection->write("Hello World!\n");
    $connection->on('data', function ($data) use ($loop, $connection) {
        echo "" . $data . "\n";
        //$connection->close();
        //$output = new React\Stream\WritableResourceStream(fopen("./client.txt", "w"),$loop);
        //$output = fopen("./client.txt", "w");
        //fwrite($output,$data);
        //$output->write("" . $data . "\n");
        while($input = fgets(STDIN, 10))
        {
            echo $input."\n";
            $connection->write($input);

        }
    });
    /*
    $input = new React\Stream\ReadableResourceStream(STDIN,$loop);
    $input->on("data",function ($data) use ($connection) {
       $connection->write($data);
    });*/
    //$output = fopen("./client.txt", "w");
    //$steam = new React\Stream\WritableResourceStream($output,$loop);
    //$connection->pipe($steam);



});

$loop->run();

最亮眼的是 将文件描述符（标准输出流 文件输出流）fd 包装成一个响应式流对象 通过pipe实现管道功能 而且生命周期相同 会同时关闭。
