<?php declare(strict_types=1);
function server_request_protocol_version(?array $serverParams = null): string
{
    $serverParams ??= $_SERVER;

    if (!isset($serverParams['SERVER_PROTOCOL'])) {
        return '1.1';
    }

    // "HTTP" "/" 1*digit "." 1*digit
    sscanf($serverParams['SERVER_PROTOCOL'], 'HTTP/%d.%d', $major, $minor);

The variable $minor seems to be never defined.

    // e.g.: HTTP/1.1
    if (isset($minor)) {

The variable $minor seems to never exist and therefore isset should always be false.

        return sprintf('%d.%d', $major, $minor);
    }

    // e.g.: HTTP/2
    if (isset($major)) {
        return sprintf('%d', $major);
    }

    return '1.1';
}
