Simple Auth - PHP

Simple & minimalist OOP interface to quickly get started with a login system

User model functions

<?php

$user = new DashboardSimpleLogin\User();

$user->connectToDb(array $db, string $sessionToken);

$user->register(string $username, string $password);
$user->login(string $username, string $password);
$user->changePassword();  // Does not work yet  (PRs open)

$user->logout();
$user->isLoggedIn();

$user->createUsersTable();

Warning: Changing a user's password does not work yet.

$dbArr = [
  'HOST' => 'localhost',
  'USER' => 'root', 
  'PASS' => '',
  'NAME' => 'simple-auth-db'
];

// Initiated the user object
$user = new DashboardSimpleLogin\User();

// Connected to the database
$connected = $user->connectToDb($dbArr, 'testToken');

// If the user is logged in
$loggedIn = $user->isLoggedIn();

// A function that is used to redirect people to pages
function returnToPage($page) {
  header('Location: ' . $page);
  die;
}
