User Authentication

A simple and customizable library for user authentication in PHP applications using a clean repository and service layer architecture.

The main purpose is to handle all complexity of user validation, authentication, properties management, and access tokens, abstracting the database layer. This class can persist user data into session (or file, memcache, etc.) between requests.

Quick Start

Installation

composer require byjg/authuser

See Installation Guide for detailed setup instructions and requirements.

Basic Usage

<?php
use ByJG\AnyDataset\Db\DatabaseExecutor;
use ByJG\AnyDataset\Db\Factory as DbFactory;
use ByJG\Authenticate\Enum\LoginField;
use ByJG\Authenticate\Model\UserModel;
use ByJG\Authenticate\Model\UserPropertiesModel;
use ByJG\Authenticate\Repository\UsersRepository;
use ByJG\Authenticate\Repository\UserPropertiesRepository;
use ByJG\Authenticate\Service\UsersService;
use ByJG\Authenticate\SessionContext;
use ByJG\Cache\Factory;

// Initialize repositories and service
$dbDriver = DbFactory::getDbInstance('mysql://user:pass@host/db');
$db = DatabaseExecutor::using($dbDriver);
$usersRepo = new UsersRepository($db, UserModel::class);
$propsRepo = new UserPropertiesRepository($db, UserPropertiesModel::class);
$users = new UsersService($usersRepo, $propsRepo, LoginField::Username);

// Create and authenticate a user
$user = $users->addUser('John Doe', 'johndoe', 'john@example.com', 'SecurePass123');
$authenticatedUser = $users->isValidUser('johndoe', 'SecurePass123');

if ($authenticatedUser !== null) {
 $sessionContext = new SessionContext(Factory::createSessionPool());
 $sessionContext->registerLogin($authenticatedUser->getUserid());
 echo "Welcome, " . $authenticatedUser->getName();
}

Set the third constructor argument to LoginField::Email if you prefer authenticating users by email instead of username.

See Getting Started for a complete introduction and Examples for more use cases.

./vendor/bin/phpunit --stderr
