What technologies should be used to create such services?

Question

PHP

Tell me what technology stack is used to create services similar to these: topvisor_ru, prodvigator_ru and the like (don't take it for advertising). Now is the time to learn something new. While I'm generally familiar with php frameworks , but I think that these things do not work on them.
There are, say, timed tasks (you can probably use cron) or is it not done on cron? Or interesting features of updating content on pages, in tables without reloading. Is this ajax or something else?
Interested in your opinion, links to this topic. I will be grateful for your help!

Answer 1

Server-Side can be written in anything. If you use data and computing resources irrationally, a productive framework will not save you. Client-Side - for everyone, but now basically it's a little bit of templating related to the choice of a framework, on the server side and a variety of JS on the client. Starting from Native JS in transit through Jquery and ending with Angular, Knockout, etc. Yes, updating data without reloading is Ajax. Some new browsers are able to use sockets, but in my opinion this technology has not been widely used due to the lack of support for ancient browsers (yes, yes. IE < 10 is quite common)

Tweak node.js
