How does php accept and process requests?

Question

PHP

I am writing a simple http server with php support. I don’t understand how it is possible to pass the request and its arguments to the puff interpreter. In the sense that it's easy to get the generated page, it's enough just to write "php filename.php" on the command line, and at the output I get a ready-made html code, which I can later pass to the user. But what to do if the code the values ​​from the POST/GET request should be used, how can it be passed to php?

Answer 1

A typical bundle for PHP is
nginx (web server) + php-fpm (FastCGI Process Manager)
That is, you can use the standard FastCGI protocol for communication.

Answer 2

Just install any local server like xampp , run your script through it. There will be something like localhost/test1 or just test1/ (without localhost), depending on how you set it up. Then you can pass your parameters, for example like this (GET):
test1?id=10&sort=5
