README

A complete user authentication library written in PHP

Installation

Use the package manager composer to install the library.

composer require riculum/php-auth

Initial setup

Credentials

The basic database settings can be set through environment variables. Add a .env file in the root of your project. Make sure the .env file is added to your .gitignore so it is not checked-in the code. By default, the library looks for the following variables:

• DB_HOST
• DB_NAME
• DB_USERNAME
• DB_PASSWORD
• DB_PREFIX

More information how to use environment variables here

Database

CREATE TABLE IF NOT EXISTS user (
    id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    uuid VARCHAR(50) NOT NULL UNIQUE,
    firstname VARCHAR(50) NOT NULL,
    lastname VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL UNIQUE,
    password VARCHAR(255) NOT NULL,
    token VARCHAR(255) NOT NULL,
    attempts TINYINT NOT NULL DEFAULT 0,
    online TINYINT NOT NULL DEFAULT 0,
    verified TINYINT NOT NULL DEFAULT 0,
    enabled TINYINT NOT NULL DEFAULT 1,
    updatedAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    createdAt DATETIME DEFAULT CURRENT_TIMESTAMP
)

Note: We recommend to set a database prefix

Configuration

Import vendor/autoload.php and load the .env settings

require_once 'vendor/autoload.php';

use Auth\Core\Authentication as Auth;

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();

Usage

Registration

Use an associative array with user data to register a new user

$user = array(
    'firstname' => 'John',
    'lastname' => 'Doe',
    'email' => 'john.doe@example.com', //must be unique
    'password' => '$2y$10$jNtkQSKNni2ELyoi9Y/lpedy7v92FYzqz5ePm1M6jPGY9hb8TCmAq',
    'token' => md5(uniqid(rand(), true))
);

try {
    echo Auth::register($user);
} catch (UserAlreadyExistsException $e) {
    echo 'User with the specified email address already exists';
} catch (Exception $e) {
    echo "Something went wrong";
}

Login

try {
    Auth::login('john.doe@example.com', '123456');
    echo 'Login successful';
} catch (InvalidEmailException | InvalidPasswordException $e) {
    echo 'Email or Password are wrong';
} catch(UserNotEnabledException $e) {
    echo 'User account has been deactivated';
} catch (TooManyAttemptsException $e) {
    echo 'Too many failed login attempts';
} catch (Exception $e) {
    echo "Something went wrong";
}

Verify

if (Auth::verify()) {
    echo "Authorization successful";
} else {
    echo "Authorization failed";
}

Logout

try {
    Auth::logout();
} catch (Exception $e) {
    echo 'Something went wrong';
}

Versioning

We adhere to semantic (major.minor.patch) versioning (https://semver.org/). This means that:

• Patch (x.x.patch) versions fix bugs
• Minor (x.minor.x) versions introduce new, backwards compatible features or improve existing code.
• Major (major.x.x) versions introduce radical changes which are not backwards compatible.

In your automation or procedure you can always safely update patch & minor versions without the risk of your application failing.
