Answer 1

Use AJAX.

Check this out: AJAX/PHP/MySQL

This edit is an answer to your latter comment--

To refresh your content every two seconds you would need to to request via ajax every two seconds. You could do so by calling your ajax function using setInterval() like so:

setInterval("ajaxFunction('someParams, 'someParams')", 2000);

But all this does is request from the server every two seconds, but refreshes whenever your sever responds, which by the way might take longer than exactly two seconds.

Answer 2

as suggested by @Babiker you can use ajax to refresh the content. But instead of updating the whole table, you can update only the cells required. in your case you can refresh the questions column.
