Pupper stands for "PHP Plus React" (PPR > Pupper). The goal is to make a Framework that takes the best of both technologies and makes them communicate bi-directionnaly.

See an example implementation

Quick start

Pupper PHP is based on Aerys, a non-blocking PHP application and Websocket framework.

Here is a quick overview of the code to get started.

use Pupper\Pupper\Event;

// Initiates WebSocket connection
$websocket = (new Pupper\Pupper\WebSocket)

    // Filter allowed clients (optional)
    ->allowOrigin('https', 'your.domain.com', 443);

    // Defines a callback for 'my_event'
    ->addEventListener('my_event', function (Event $event) {
    
        // Dispatches to all clients
        $websocket->broadcastEvent(
            new Event('notify_all', 'Something has happened!');
        );
    
        // Dispatches to the client that triggered the callback
        return (new Event)
            ->setName('operation_done')
            ->setValue('Your value was ' . $event->getValue());

    });

$router = Aerys\router()->route('GET', '/', Aerys\websocket($websocket));

// Exposes the websocket to the 1337 port
return (new Aerys\Host)->use($router)->expose('*', 1337);

API

WebSocket

WebSocket is the class that initiates the WebSocket on the PHP side.

addListener

addListener takes the event name as first parameter, and a callback function as a second parameter.

If you return an Event, it will be dispatched to the client that triggered the callback.

use Pupper\Pupper\Event;

$websocket = (new Pupper\Pupper\WebSocket)
    ->addEventListener('custom', function (Event $event) {
        return (new Event)
            ->setName('custom')
            ->setValue('From PHP: ' . $event->getValue());
    });

broadcastEvent

broadcastEvent dispatches an event to all the clients.

use Pupper\Pupper\Event;

$websocket = (new Pupper\Pupper\WebSocket)
    ->addEventListener('player_has_joined', function (Event $event) {
        $websocket->broadcastEvent(
            'player_count_updated',
            'A new player has joined!'
        );
    });

Client filtering

Set WebSocket's constructor's protocol, host and port parameters to restrict the access to your websocket .

$websocket = (new \Pupper\WebSocket)->allowOrigin('https', 'your.domain.com', 80);

Event

Event represents an event from the PHP side.

Read

Event has getName() and getValue() methods to read the event's name and value.

use Pupper\Pupper\Event;

function (Event $event) {
    echo $event->getName();
    echo $event->getValue();
});

Write

Event has setName() and setValue() methods to write the event's name and value.

use Pupper\Pupper\Event;

$event = (new Event)
    ->setName('hello_event')
    ->setValue('Hello from PHP!');

Construct

Event's constructor also accepts the event's name and value as parameters.

use Pupper\Pupper\Event;

$event = new Event(
    'hello_event', 
    'Hello from PHP!'
);
