Socket Component

Library for building an evented socket server.

The socket component provides a more usable interface for a socket-layer server or client based on the EventLoop and Stream components.

Server

The server can listen on a port and will emit a connection event whenever a client connects.

Connection

The connection is a readable and writable stream. It can be used in a server or in a client context.

Usage

Here is a server that closes the connection if you send it anything.

$loop = React\EventLoop\Factory::create();

$socket = new React\Socket\Server($loop);
$socket->on('connection', function ($conn) {
    $conn->write("Hello there!\n");
    $conn->write("Welcome to this amazing server!\n");
    $conn->write("Here's a tip: don't say anything.\n");

    $conn->on('data', function ($data) use ($conn) {
        $conn->close();
    });
});
$socket->listen(1337);

$loop->run();

Here's a client that outputs the output of said server and then attempts to send it a string.

$loop = React\EventLoop\Factory::create();

$client = stream_socket_client('tcp://127.0.0.1:1337');
$conn = new React\Socket\Connection($client, $loop);
$conn->pipe(new React\Stream\Stream(STDOUT, $loop));
$conn->write("Hello World!\n");

$loop->run();
