Please read this document to learn how to install and use this package to make PHP generate user tokens to access the Agora services.

PHP Agora Token Builder

This package is a Composer-friendly rewrite of Agora's PHP token generator. It provides a simple and modern way to generate Agora Access Tokens (v2.1.0) and Dynamic Keys (v2.0.2 or earlier) for authenticating users in real-time communication applications.

> This rewrite preserves the integrity of Agora's token-signing logic while introducing improvements for better structure, developer experience, and Composer compatibility.

Features and Enhancements

• Type Hints: Enforced strict typing for all method parameters and return types, making it IDE and static-analysis friendly.
• Agora Client Class: Centralized class for initializing your `App ID` and `App Certificate`.
• User Model: Object-oriented structure for setting user-specific values like UID, role, privileges, and token expiration.
• Role Constants: Easy-to-read and self-documented roles for RTC and RTM users.
• Privilege Constants: Easily manage supported privileges using named constants.
• Namespace Organization: Organized into PHP namespaces for clarity and autoloading support.
• Exception Handling: Errors now throw meaningful exceptions (e.g., missing credentials), improving debugging and robustness.
• Composer Compatible: Easily install and autoload with Composer.

Class Refactor & Naming Convention

To improve clarity and follow modern naming conventions, we have renamed certain classes. The legacy version now uses a Legacy suffix, while the latest version drops the previous 2 suffix:

| Old Class Name | New Class Name | Description | | --------------- | ------------------------------------ | ---------------------------------------- | | AccessToken | AccessTokenLegacy | Agora AccessToken Version 006 (legacy) | | AccessToken2 | AccessToken | Agora AccessToken Version 007 (latest) | | RtcTokenBuilder | RtcTokenLegacy | Builder for AccessToken 006 | | RtcTokenBuilder2 | RtcToken | Builder for AccessToken 007 | | RtmTokenBuilder | RtmTokenLegacy | Builder for RTM token AccessTokenLegacy | | RtmTokenBuilder2 | RtmToken | Builder for RTM token AccessToken |

> This ensures the default token builder always targets the most up-to-date version, while legacy usage remains supported but explicitly labeled.

Target Versions

This package supports:

• AccessToken Version 006
• AccessToken2 Version 007

Installation

Install the package via Composer:

Class Namespaces

Below is a breakdown of the namespaces and classes provided by the package:

Core Components

• Peterujah\Agora\Agora Manages the Agora `App ID`, `App Certificate`, default channel name, user role, and token expiration setup.
• Peterujah\Agora\User Represents the user identity. Handles UID, channel name, user role, and privilege assignment.

• Peterujah\Agora\Roles Defines constants for user roles used in RTC and RTM tokens:

  * `RTC_PUBLISHER`, `RTC_SUBSCRIBER`, `RTC_ATTENDEE`, `RTC_ADMIN`, `RTM_USER`

• Peterujah\Agora\Privileges Contains all supported privilege constants for APAAS, CHAT, RTC and RTM services.

  * `APAAS_ROOM_USER`, `RTC_JOIN_CHANNEL`, `PERMISSIONS`

• Peterujah\Agora\Message Handles basic agora message payload packing.
• Peterujah\Agora\Util Utility helpers used internally for token formatting or time-based calculations.
• Peterujah\Agora\BaseService Shared logic base for service-related classes (e.g., default token generators).

• Peterujah\Agora\func Procedural utility functions for:

  * `DynamicKey4`, `DynamicKey5`, and `SignalingToken` generation.

Agora Access Token Handlers

• Peterujah\Agora\Tokens\AccessTokenLegacy Builder for legacy AccessToken (`006`).
• Peterujah\Agora\Tokens\AccessToken Builder for modern AccessToken2 (`007`) format.

Token Builders (Service Specific)

Each token builder generates a scoped access token for a specific Agora service:

• Peterujah\Agora\Builders\ApaasToken ? For Agora Platform-as-a-Service (APaaS).
• Peterujah\Agora\Builders\ChatToken ? For Chat/Messaging token generation.
• Peterujah\Agora\Builders\EducationToken ? For Agora?s Education SDK token support.
• Peterujah\Agora\Builders\FpaToken ? For First-Packet Acceleration (FPA).
• Peterujah\Agora\Builders\RtcToken ? For RTC AccessToken (`007`) generation.
• Peterujah\Agora\Builders\RtcTokenLegacy ? For RTC AccessToken2 (`006`) generation.
• Peterujah\Agora\Builders\RtmToken ? For RTM AccessToken (`007`).
• Peterujah\Agora\Builders\RtmTokenLegacy ? For RTM AccessToken2 (`006`).

Agora Service Interfaces

High-level abstractions that encapsulate Agora service-specific token generation:

• Peterujah\Agora\Services\Apaas ? Handles APaaS token creation.
• Peterujah\Agora\Services\Chat ? Token management for Chat services.
• Peterujah\Agora\Services\Fpa ? Handles First-Packet Acceleration service tokens.
• Peterujah\Agora\Services\Rtc ? Manages RTC token generation via builder classes.
• Peterujah\Agora\Services\Rtm ? Manages RTM token generation via builder classes.

Usage Examples

You can generate tokens locally using your Agora App ID and App Certificate.

Basic Token Generation Example

use Peterujah\Agora\Agora;
use Peterujah\Agora\User;
use Peterujah\Agora\Roles;
use Peterujah\Agora\Builders\RtcToken;

// Example inputs
$channelName = "7d72365eb983485397e3e3f9d460bdda";
$uid = 2882341273;
$uidStr = "2882341273";
$maxTokenLive = 3600;

// Generate privilege expiration timestamp (UTC)
$currentTimestamp = (new DateTime("now", new DateTimeZone('UTC')))->getTimestamp();
$privilegeExpiredTs = $currentTimestamp + $maxTokenLive;

// Initialize Agora client using environment variables
$client = new Agora(
  getenv("AGORA_APP_ID"),           // Set this in your environment
  getenv("AGORA_APP_CERTIFICATE")   // Set this in your environment
);
$client->setExpiration($privilegeExpiredTs); // Agora Token expiration

// User using UID (int)
$user1 = (new User($uid))
  ->setPrivilegeExpire($privilegeExpiredTs)
  ->setChannel($channelName)
  ->setRole(Roles::RTC_PUBLISHER);

// Generate RTC token using legacy builder (AccessToken v007)
$token1 = RtcToken::buildTokenWithUid($client, $user1);
echo 'Token with int UID: ' . $token1 . PHP_EOL;

// User using User Account (string)
$user2 = (new User($uidStr))
  ->setPrivilegeExpire($privilegeExpiredTs)
  ->setChannel($channelName)
  ->setRole(Roles::RTC_PUBLISHER);

// Generate RTC token using legacy builder with user account
$token2 = RtcToken::buildTokenWithUserAccount($client, $user2);
echo 'Token with user account: ' . $token2 . PHP_EOL;

> Use RtcToken instead of RtcTokenLegacy if you're working with AccessToken2 (v007).
