I did not go thru the code fully, so I leave that to others to comment
on.
(isset($_POST[’login’]))... refers to detecting that the form has been
submitted. The value of $_POST[’login’] would be set when the submit
button has been pressed. As your form and your form-processing logic
are both on the same script, this is the way of detecting when $_POST
values are present for processing
