[quote author="tekhneek" date="1242047286"]I could be wrong, but wouldn't this achieve the same thing with less code?

Code:

$query = $this->db->get_where('users', array('username' => $username, 'password' => $password));
if ($query->num_rows() === 1) {
   return $query;
} else {
   return false;
}

It would acheive the same with less code, but sometimes its better to be a bit more verbose and a little more clear

I could probably do it all in 1 line of code if I wanted, but if it makes it complicated and difficult to understand, whats the point?
(I know you're example isn't complicated per se, but I'm just making the point)
