Why doesn't php://stdin work in nginx?

Question

PHP

$stdin = fopen('php://stdin', 'r');
$line = trim(fgets($stdin));
var_dump($line);

Doesn't work under nginx. How to be?)
file_get_contents('php://input') behaves in the same way Let me
clarify the question. There is a lib for asterisk - phpagi . Actually, she does not want to start under nginx, hangs on fgets

Answer 1

Wait. stdin is the input stream. As far as I know, only console PHP has such an implementation.
Perhaps you meant file_get_contents('php://input') - or did I misunderstand?

Answer 2

php://stdin - standard input stream, when working with nginx (php-fpm or cgi) nothing can be read from it.
php://input - POST data can be read from this stream
Judging by the description of the specified library, it works only through the CLI.
