<?php
session_start();

$GLOBALS ['config'] = array(
    'mysql' => array(
        'host' => '127.0.0.1',
        'username' => 'root',
        'password' => '',

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

});

require_once 'functions/sanitize.php';
if(Cookie::exists(Config::get('remember/cookie_name')) && !Session::exists(Config::get('session/session_name'))) {
    $hash = Cookie::get(Config::get('remember/cookie_name'));
    $hashCheck = DB::getInstance()->get('users_session', array('hash', '=', $hash));
    if($hashCheck->count()) {
        $user = new User($hashCheck->first()->user_id);
        $user->login();
    }
}
?>

</div>

The problem is that you are attempting to register an anonymous function using spl_autoload_register(), but as you told that you are using PHP5.2 on your web server.

Unfortunately PHP < 5.3 does not support anonymous functions. You need to write a "regular" function:

function my_autoload($class) {
    require_once 'classes/' . $class . '.php';
}

spl_autoload_register('my_autoload');

This will work on PHP >= 5.3 as well.
