How to save information about pressing a button on the server?

Question

PHP

Hello. Tell me please.

Task: there is a landing page, the client has several employees, each has their own phone number and email address (they are scattered over feedback forms, whatsapp icons). Let's say Peter - 11 11 11; [email protected], Sergey - 22 22 22 [email protected], etc.

If visitor-1 went to the site and clicked on the whatsapp icon or the "call me back" button, then Peter's phone and email should change to Sergey for visitor-2, if visitor-1 went to the site and did nothing, the data should not change until visitor-1 or any other user clicks on the button.

How to implement it? As I understand it, you need to interact with the server and save information there, localstorage is only for one visitor, and not for everyone.

Yes . At the moment of clicking, send a request to the server and delay the reaction until a response from the server arrives. On the server, there will be the usual order: Petya, Vasya, Petya, Vasya, etc. Thus, whatever the pings, the order will be quite strict. And if it was not possible to reach the server, then something like Radnom (Petya, Vasya) can be used as a reaction.
