LiveKit Server API for PHP

PHP APIs to manage rooms and to create access tokens. This library is designed to work with livekit-server. Use it with a PHP backend to manage access to LiveKit.

Installation

Requirements

• php: >= 8

Composer

composer require agence104/livekit-server-sdk

Usage

Environment Variables

You may store credentials in environment variables. If api-key or api-secret is not passed in when creating a RoomServiceClient or AccessToken, the values in the following env vars will be used:

• LIVEKIT_API_KEY
• LIVEKIT_API_SECRET

Creating Access Tokens

Creating a token for participant to join a room.

// If this room doesn't exist, it'll be automatically created when the first
// client joins.
$roomName = 'name-of-room';
// The identifier to be used for participant.
$participantName = 'user-name';

// Define the token options.
$tokenOptions = (new AccessTokenOptions())
  ->setIdentity($participantName);

// Define the video grants.
$videoGrant = (new VideoGrant())
  ->setRoomJoin();
  ->setRoomName($roomName);

// Initialize and fetch the JWT Token. 
$token = (new AccessToken('api-key', 'secret-key'))
  ->init($tokenOptions)
  ->setGrant($videoGrant)
  ->toJwt();

By default, the token expires after 6 hours. you may override this by passing in ttl in the access token options. ttl is expressed in seconds (as number) .

Parsing the Access Tokens

Converting the JWT Token into a ClaimGrants.

// Initialize and parse the JWT Token. 
$claimGrants = (new AccessToken('api-key', 'secret-key'))  
  ->fromJwt($token);

Permissions in Access Tokens

It's possible to customize the permissions of each participant:

$videoGrant = (new VideoGrant())
  ->setRoomJoin() // TRUE by default.
  ->setRoomName('name-of-room')
  ->setCanPublish(FALSE)
  ->setCanSubscribe() // TRUE by default.
  ->setGrant($videoGrant);

This will allow the participant to subscribe to tracks, but not publish their own to the room.

Managing Rooms

RoomServiceClient gives you APIs to list, create, and delete rooms. It also requires a pair of api key/secret key to operate.

$host = 'https://my.livekit.host';
$svc = new RoomServiceClient($host, 'api-key', 'secret-key');

// List rooms.
$rooms = $svc->listRooms();

// Create a new room.
$opts = (new RoomCreateOptions())
  ->setName('myroom')
  ->setEmptyTimeout(10)
  ->setMaxParticipants(20);
$room = $svc->createRoom($opts);

// Delete a room.
$svc->deleteRoom('myroom');
