Well I have been playing around with classes lately:

I know this is not secure, it is not meant to be.

save this as your login.php:

<?php
$action = $_GET[action];
if ($action == "login") {
include "class.php";
$user = new authentication;
$user->correctu = "Caleb";
$user->correctp = "testing";
$user->success = "testing.php";
$user->username = $_POST[username];
$user->password = $_POST[password];
$user->start_login();
exit;
}
?>

<title>Simple Login</title>
<style type="text/css">

</head>

<body>
<span class="style1"><u><strong>Simple user login</strong></u>
<br>
<br>
</span>
<form action="?action=login" method="post" name="login_form" class="style1">
<fieldset><legend>Details</legend>
<br>
<strong>Username:<br>
<label>
<input name="username" type="text" id="username" size="30">
</label>
<br>
<br>
Password:</strong>
<br>
<strong>
<input name="password" type="password" id="password" size="30">
</strong><br>
<br>
<label>
<input type="submit" name="Submit" value=" Login ">
</label>
</fieldset>
</form>
</body>
</html>

Save this as your class.php:

<?php
class authentication {
var $username;
var $password;
var $correctu;
var $correctp;
var $success;

function clean($value) {
return strip_tags(htmlspecialchars(addslashes(stripslashe s($value))));
}

function go($url) {
echo "<meta http-equiv=\"refresh\" content=\"0;url=$url\">";
}

function check_username() {
if ($this->username != $this->correctu) {
echo "Sorry, that is an incorrect username!";
exit;
}
$this->check_password();
}

function check_password() {
if ($this->password != $this->correctp) {
echo "Sorry, that password was incorrect!";
exit;
}
$this->go($this->success);
}

function start_login() {
$this->username = $this->clean($this->username);
$this->password = $this->clean($this->password);
if ($this->username == "" || $this->password == "") {
echo "Please fill in all correct fields!";
exit;
}
$this->check_username();
}
}
?>

Its just a simple thing, classes save a HUGE amount of time :)
