PHP (server-side)

Trigger events from any PHP backend — Laravel, Symfony, plain PHP, anything.

Install

composer require pusher/pusher-php-server

Trigger an event

<?php
require __DIR__ . '/vendor/autoload.php';
 
$pusher = new Pusher\Pusher(
    'YOUR_APP_KEY',
    'YOUR_APP_SECRET',
    'YOUR_APP_ID',
    [
        'host'    => 'ws-sa.mawjly.com',
        'port'    => 443,
        'scheme'  => 'https',
        'cluster' => 'sa',
        'useTLS'  => true,
    ],
);
 
$pusher->trigger('chat', 'message', [
    'user' => 'alice',
    'text' => 'Hello from PHP!',
]);

Batch trigger (up to 10 events per call)

$pusher->triggerBatch([
    ['name' => 'message', 'channel' => 'chat',  'data' => ['text' => 'one']],
    ['name' => 'message', 'channel' => 'chat',  'data' => ['text' => 'two']],
    ['name' => 'typing',  'channel' => 'chat',  'data' => ['user' => 'alice']],
]);

Channel info

$res = $pusher->getChannels(['filter_by_prefix' => 'presence-']);
// $res->channels => ['presence-room-1' => ['user_count' => 3], ...]
 
$info = $pusher->getChannelInfo('presence-room-1', ['info' => 'user_count,subscription_count']);
 
$members = $pusher->get('/channels/presence-room-1/users');

Authorize a private / presence subscription

If your client subscribes to private- or presence- channels, you expose a /broadcasting/auth endpoint that signs the subscription with your secret.

$auth = $pusher->authorizeChannel(
    $_POST['channel_name'],
    $_POST['socket_id'],
);
echo $auth; // {"auth":"<key>:<hex_signature>"}

For presence channels, also pass the user data:

$auth = $pusher->authorizePresenceChannel(
    $_POST['channel_name'],
    $_POST['socket_id'],
    (string) $userId,
    [
        'name'   => $user->name,
        'avatar' => $user->avatar_url,
    ],
);

See Authorization endpoints for full examples in PHP, Node, and Laravel.
