Every time you do an AJAX call, a new independent script is launched server side.

It means that it has no memory of the previous calls and of the previous array entries (It creates a new one, basically).

You could maybe achieve that by storing values in a JSON (or whatever) file that you change every time, or directly store the values in database.
