Async Simple Service Discovery Protocol (SSDP), built on top of ReactPHP.

SSDP is part of Universal Plug and Play (UPnP) and is commonly used to discover network services on home networks without requiring any manual configuration, such as automatically discovering printers, multimedia devices and network routers.

This library implements SSDP as defined in the UPnP device architecture definition (PDF) and uses HTTP over Multicast UDP (HTTPMU) as defined in the IETF draft. As an alternative, some devices use DNS-Based Service Discovery (DNS-SD) instead as defined in RFC 6763.

Quickstart example

Once installed, you can use the following code to search all available UPnP devices in your network:


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

$client = new Clue\React\Ssdp\Client();

    function () {
        echo 'Search completed' . PHP_EOL;
    function(Exception $e) {
        echo 'There was an error searching for devices: ' . $e . PHP_EOL;
    function ($progress) {
        echo 'Found a device: ' . PHP_EOL;
        echo PHP_EOL;

The recommended way to install this library is through composer. New to composer?

    "require": {
        "clue/ssdp-react": "dev-master"

This project aims to run on any platform and thus does not require any PHP extensions and supports running on legacy PHP 5.3 through current PHP 8+ and HHVM. It's highly recommended to use the latest supported PHP version for this project.


To run the test suite, you first need to clone this repo and then install all dependencies through Composer:
