Refresh list of Online User for certain interval with MySql
lets figure that I want to make a social web media like facebook which user can create and log in with their account. The user can see in a navigation bar which friends are online and offline.
Is there a way to update online and offline users without refreshing the page for a certain interval such as every 10 minute it will query data from database and update the data ???
