How to update data?

Question

PHP

I have Api of one site, from it I extract (using php) some data that is updated for example every 3 seconds, so that they are updated on my site, I need to refresh the page, but I need this to happen without reloading.
This is the crux of my question. Thanks in advance.

Answer 1

As for php itself, if you need to save data somewhere, then you need to use cron or a task scheduler (I won’t give examples, since I don’t write in PHP anymore).
And if purely for display, use looped ajax requests (as an option - setInterval in jquery)

Answer 2

I'm more confident that the response will be only ajax
