There is a div on the website that will show the data received from server side, for example, Let's say showing the current number of registered users in the databases. This number will keep changing in an unknown period of time. For example, the number could be the same in 10 hours, and it could increment by 1000 in 10 minutes.
My first question is, what is the best approach to do this functionality so that website can always show the latest or almost latest value of this data?
My second question is, if this is not a good approach, what else can I do to achieve the same goal. I was thinking about using the other way around. For example, if there is update in the server side, then use PHP in the server side to push this update to client side, or even directly change the data shown in the HTML using PHP scripting. Is this possible? if it is, is this a good approach?
Any codes or examples provided would be really appreciated.
