You have a better example here: Easy login script without database
<?php
session_start();
$userinfo = array(
'user1'=>'password1',
'user2'=>'password2'
);
if(isset($_GET['logout'])) {
$_SESSION['username'] = '';
header('Location: ' . $_SERVER['PHP_SELF']);
}
if(isset($_POST['username'])) {
if($userinfo[$_POST['username']] == $_POST['password']) {
$_SESSION['username'] = $_POST['username'];
}else {
//Invalid Login
}
}
?>
