Build Status Latest Version

PHP library to communicate with Centrifugo v5 HTTP API (for Centrifugo v4 use phpcent v5.x, for Centrifugo v3 use phpcent v4.x).

Library is published on the Composer:

composer require centrifugal/phpcent:~6.0

See Centrifugo server API documentation.

Basic Usage:

$client = new \phpcent\Client("http://localhost:8000/api");
$client->setApiKey("Centrifugo API key");
$client->publish("channel", ["message" => "Hello World"]);

You can use phpcent to create connection token (JWT):

$token = $client->setSecret("Centrifugo secret key")->generateConnectionToken($userId);

Connection token that will be valid for 5 minutes:

$token = $client->setSecret("Centrifugo secret key")->generateConnectionToken($userId, time() + 5*60);

It's also possible to generate channel subscription token:

$token = $client->setSecret("Centrifugo secret key")->generateSubscriptionToken($userId, $channel);

It's also possible to generate channel subscription token with expiration time, for example token for 30 mins:

$token = $client->setSecret("Centrifugo secret key")->generateSubscriptionToken($userId, $channel, time() + 30*60);

Also API key and secret can be set in constructor:

$client = new \phpcent\Client("http://localhost:8000/api", "<API key>", "<secret key>");


$client->setConnectTimeoutOption(0); // Seconds | 0 = never
$client->setTimeoutOption(2); // Seconds

All available API methods:

$response = $client->publish($channel, $data);
$response = $client->broadcast($channels, $data);
$response = $client->unsubscribe($channel, $userId);
$response = $client->disconnect($userId);
$response = $client->presence($channel);
$response = $client->presenceStats($channel);
$response = $client->history($channel);
$response = $client->historyRemove($channel);
$response = $client->channels();
$response = $client->info();

To use assoc option while decoding JSON in response:



In case if your Centrifugo server has invalid SSL certificate, you can use:


You can also use self signed certificate in safe manner:

$client = new \phpcent\Client("https://localhost:8000/api");
$client->setCAPath("/ca/path"); // if you need.

Note: Certificate must match with host name in Client address (localhost in example above).

DNS Resolution

This error may indicate your system is having trouble resolving IPv6 addresses:

cURL error: Resolving timed out after [value] milliseconds

By default, both IPv4 and IPv6 addresses will attempt to be resolved. You can force it to only resolve IPv4 addresses with:




The provided PHPUnit tests assume that a local Centrifugo server is running and available at port 8000. This can be accomplished using Docker and the official Centrifugo image.

# Install package dependencies.
$ composer install

# The following command starts a Centrifugo server running in a background Docker container.
$ docker run -d -p 8000:8000 --name centrifugo centrifugo/centrifugo centrifugo --api_insecure

# Run the test suite.
$ vendor/bin/phpunit

# Shut down the Centrifugo container.
$ docker stop centrifugo
