点击更改所有用户的div内容

Question

I want to change the content of a div when I click a button. I can do this easily with jquery but it is only on my side. I want it to be changed for all the users if they connect to the page or refresh the page. How can I do that? I understand that it has to be with php (server side script). Any ideas? To make it simple -> click of a button -> change div for all visitors of that page (after they refresh the page of course).

Answer 1

what I would do is:

1. when button clikced: store the new value to the database.
2. set a timeout to refresh the div every X seconds using AJAX (javascript).
