class User
{
public static logon ($username, $password)
{
// Example query. You will want to protect against SQL
// injection here.
$q = "SELECT blah
FROM blah
WHERE username=$username
AND password=$password";
$result = run_query($q);

if (!$result)
return NULL;

$user = new User;
$user->load_data(/* blah */);
return $user;
}
}

This is an example of a User "factory". See "factory design pattern" in the
PHP manual. To use it:

$logged_in_user = User::logon($_POST['un'], $_POST['pw']);
if (!$logged_in_user)
echo "Login failed.";
