Где найти простой скрипт авторизации PHP7+MySQL+SESSION+COOKIES?

<?php
if (empty($_POST['email']) || empty($_POST['pass'])) {
    die ("Enter credentials");
}
require 'pdo.php';
$stmt = $pdo->prepare("SELECT * FROM users WHERE email = ?");
$stmt->execute([$_POST['email']]);
$user = $stmt->fetch();

if ($user && password_verify($_POST['pass'], $user['pass']))
{
    session_start();
    $_SESSION['user'] = $user;
    header("Location: /dashboard.php");
    exit;
} else {
    die ("Wrong credentials");
}

Весь интернет перерыл в поисках простейшей авторизации на PHP7 и MySQL с сессиями и куками

class UserController extend BaseController 
{
....
public function loginAction(){
    $user = $this->currentUser();
    $user->login($this->params->post('login'),$this->params->post('pass'));
    if($user->isLoggedIn()){
        redirect($someURL);
    }
    else{
         doErrorStuff();
    }
}
}

function Auth()
  {
    $user = Util::alphaNum(Request::post("user"));
    $password = Util::alphaNum(Request::post("password"));

    $sql = Server::connect();

    $user = $sql->fetchOne("SELECT id FROM user WHERE user = :user AND password = :password", [
      "user" => $user,
      "password" => $password,
    ]);

    if (is_null($user)) {
      throw new \UserAuthWrongLoginException();
    }

    $_SESSION["user"] = $user->id;
  }
