How to simulate form submission via post php?

Question

PHP

I have several variables that I need to send via post using php with a further transition to the sending page.
How to implement this?
The main condition is the transition to the site along with POST.

To begin with, remove the word "specialist" from the signature and decompose the question. The answer is on the surface: phpfaq.ru/newbie/na_tanke
