ReactPHP Compatibility

Learn how to use any ReactPHP library and make it compatible with Amp.

amphp/react-adapter makes any ReactPHP library compatible with Amp v2.

If you’re using AMPHP v3, have a look at revolt/event-loop-adapter-react instead.


This package can be installed as a Composer dependency.

composer require amphp/react-adapter


Everywhere where a ReactPHP library requires an instance of LoopInterface, you pass ReactAdapter::get() to run the ReactPHP library on Amp’s event loop.


require 'vendor/autoload.php';

use Amp\Loop;
use Amp\ReactAdapter\ReactAdapter;

Loop::run(function () {
    $app = function ($request, $response) {
        $response->writeHead(200, array('Content-Type' => 'text/plain'));
        $response->end("Hello World\n");

    $socket = new React\Socket\Server(ReactAdapter::get());
    $http = new React\Http\Server($socket, ReactAdapter::get());

    $http->on('request', $app);
    echo "Server running at\n";


You can also use the adapter to run ReactPHP apps on an Amp event loop implementation without relying on Amp’s global event loop.

$loop = new Amp\ReactAdapter\ReactAdapter((new Amp\Loop\DriverFactory)->create());
