This is just a basic Login/Register Script, the CSS coding would need to be done by you.
login.php
<?php
$error = false;
if(isset($_POST['login'])){
$username = preg_replace('/[^A-Za-z]/', '', $_POST['username']);
$password = md5($_POST['password']);
if(file_exists('NAME OF DIRECTORY TO STORE USER INFO./' . $username . '.xml')){
$xml = new SimpleXMLElement('users/' . $username . '.xml', 0, true);
if($password == $xml->password){
session_start();
$_SESSION['username'] = $username;
header('Location: index.php');
die;
}
}
$error = true;
}
?>
