Live data from database to shown on webpage without ajax
I'm trying to add some live data to my webpage, I know about ajax, but I do not like that it calls every time to receive the data.
I'm looking for a solution similar to the one DO used on the homepage with how many dropblets that had been spinned up. the counter kept raising after page load
How did they make that?, I don't remember seeing my browser calling anything all the time.
I prefer a solution working with PHP.
