The question is how to implement sending a form or text through php to another site?

Question

PHP

Such a task is worth it! There is one site in which the client chooses what he needs and presses the button to order! and a notification should appear in my admin panel that the client has chosen such a product or item. The task is so that when the client clicks in the panel, it should instantly appear what the client has selected. I can’t figure out what to write all this on, I know html, but at the expense of PHP, a simple user). And they say that you need to somehow use php

Answer 1

Well, in theory, you can write a script that requests data every, say, 15 seconds ... sets itself a timestamp and shows the data ... in theory, it should suit a person.

Answer 2

I may not have understood the question quite correctly, but what prevents PHP from sending selection requests via curl, and tracking on the client site?
