How to click input on another site?

Question

PHP

Hello!
There is such a question
. Here I have complete information about the block on which you need to click, but it is located on someone else's hosting, how can this be done and what are the ways?
I'm not asking for a complete solution to the problem, I just need to understand how this can be done, what technologies?
