<?php 

session_start();

$GLOBALS['config'] = array(

'mysql' => array(
    'host' => '127.0.0.1',
    'username' => 'root',
    'password' => '',
    'db' => 'oop'),

'remember' => array(
    'cookie_name' => 'hash',
    'cookie_expiry' => 604800),

'session' => array(
    'session_name' => 'user')
);

spl_autoload_register(function($class) {
    require_once 'classes/' . $class …
