Answer 1

You can use session variable to store those values, when there's nothing stored in session, create the session variables, when it is already set in session, retrieve back the value, so your values become persistent.

Another feasible way would be to use hidden input elements, each these element is used to store previous value of a variable, you use echo to output these elements dynamically into HTML body along with their values.
