ReactPHP - error

1

I'm trying to run a test using ReactPHP but it keeps coming back, so anyone can help me:

Fatal error: Uncaught TypeError: Argument 1 passed to React\Socket\Server::__construct() must implement interface React\EventLoop\LoopInterface, string given, called in C:\xampp\htdocs3.php on line 5 and defined in C:\xampp\htdocs3\vendor\react\socket\src\Server.php:68 Stack trace: #0 C:\xampp\htdocs3.php(5): React\Socket\Server->__construct('127.0.0.1:8080', Object(React\EventLoop\StreamSelectLoop)) #1 {main} thrown in C:\xampp\htdocs3\vendor\react\socket\src\Server.php on line 68

code:

<?php
require __DIR__.'/vendor/autoload.php';
$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
$socket->on('connection', function (ConnectionInterface $connection) {
    $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) {
        $connection->close();
    });
});

$loop->run();
?>

code from the other folder

<?php

namespace React\Socket;

use Evenement\EventEmitter;
use React\EventLoop\LoopInterface;

/**
 * The 'Server' class implements the 'ServerInterface' and
 * is responsible for accepting plaintext TCP/IP connections.
 *
 * Whenever a client connects, it will emit a 'connection' event with a connection
 * instance implementing 'ConnectionInterface':
 *
 * '''php
 * $server->on('connection', function (ConnectionInterface $connection) {
 *     echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
 *     $connection->write('hello there!' . PHP_EOL);
 *     …
 * });
 * '''
 *
 * See also the 'ServerInterface' for more details.
 *
 * Note that the 'Server' class is a concrete implementation for TCP/IP sockets.
 * If you want to typehint in your higher-level protocol implementation, you SHOULD
 * use the generic 'ServerInterface' instead.
 *
 * @see ServerInterface
 * @see ConnectionInterface
