exmple :-

1. model.php
2. class.php
3. hook.php
4. index.phtml

with model i get database information. with class im calculating online friend list as a array using array_intersect. and with hook i render to index.phtml. in phtml i use foreach loop and get the result to my online friendlist.

Here is my function im getting online user list with this. but if new user come to online i must refresh the page to see new online member. i want to make it auto update list. with ajax or something. can someone give me example how can i do that?

Answer 1

You may use setTimeout function, either to reload the page or to call ajax and update the page content. here is small idea.

setTimeout(function(){
// Do code here for reload/ajax here.
}, 3000);

Answer 2

I believe the problem is more involved than merely front-end.

You will need the client to establish a socket with your server such that your server is able to constantly inform users of new online users. Otherwise, using a stay-alive connection with the server can also help, and use some jQuery to handle user list updates.
