Request_parse_body returns nothing when something has accessed php://input stream before it

[iparnamaa]

From manual page: https://php.net/function.request-parse-body

---

$_POST array is always empty even it there is correct payload in request body:

if ($_SERVER['REQUEST_METHOD'] === 'PUT' && intval($_SERVER['CONTENT_LENGTH']) > 0 && str_starts_with($_SERVER['CONTENT_TYPE'], 'application/x-www-form-urlencoded')) {
    $backup = file_get_contents('php://input');
    [$_POST,$_FILES] = request_parse_body();
}
