What you are looking for is really ajax, this is mainly done in javascript,
the script that receives the data or sends the data can of course be simple
php scripts.
1. you load a page with ajax.
2. action on the page executes the ajax function (to send or fetch data)
3. the php script will process the request and send a result back to the page
4. the ajax function will process the reply and displaying the result.
if you reload the page, it can be possible to have all the previous data
there, check boxes checked and so on, if the changes are always sent back and
stored in a session or stored in a normal cookie (the later can be done
without really using ajax).
For the javascript part, you have to seek out other places to discuss that,
when it comes to the php part, it's exactly the same as it would have been
with a standard form.
