login script with a few options?

[NewFate]

Hi,
im a total newbie to php/mysql
i was wondering if any of you had any login scripts with a few simple functions so i could look and try and understand how things work
i tryed looking at other sites trying to teach how php works(webmonkey being one) and it just confuses me to be honest..
thanks in advance

here is something really really simple..

$user = 'bob';
$pass = 'abc';

if($_POST['username'] == $user && $_POST['password'] == $pass) {
echo 'Login successfull';
} else {
echo 'Incorrect username or password';
}
