Question

Live data from database to shown on webpage without ajax

Hello,

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.

IIRC, DigitalOcean uses Ember in quite a few areas which requires NodeJS and implements jQuery which uses Javascript, all of which are capable of using AJAX to process background requests for data.

A NodeJS app, for example, could read from a JSON file on startup. That same JSON file could be updated by another portion of the app which then updates the counter. Since NodeJS is the web server, updates to such would not require a page refresh nor spawn a noticeable background processes. In the case of this example app, the “background” process would be handled by another part of the app.

Without Javascript, jQuery, AJAX or NodeJS, PHP alone would not be able to update asynchronously as it simply doesn’t provide a way to do so natively. You could opt to use React (link), which is a PHP library, though then you’d be diving in to socket connections via PHP (an example of such is actually on the homepage).
