PHP version upgrade / Upnp script error with XMLReader

[shikasta-net]

I have been trying to get DLNA working with a docker container (happy to share more on this as it's not trivial to get the networking right).
While debugging I found:

(log.lib) -> [Error] Non-static method XMLReader::XML() should not be called statically in file /var/www/src/Module/Api/Upnp_Api.php(297)
(log.lib) -> [Runtime Error] XMLReader::read(): Load Data before trying to read in file /var/www/src/Module/Api/Upnp_Api.php(302)

This is related to

public static function parseUPnPRequest($prmRequest)
    {
        $retArr = array();
        $reader = new XMLReader();
        $result = XMLReader::XML($prmRequest);

XMLReader is not static until PHP 8. I've tried using the instance instead of static call; the error is fixed but I'm still getting no listings on the client, so I'll give the updated PHP version a try. When I change the line to $result = $reader->XML($prmRequest); everything works, so the container just needs upgrading to PHP8.

I tried building my own image from the Dockerfile so I can try updating it to php8 but it stalls around dpkg-reconfigure libdvd-pkg with exit code 2.

i'm going to update docker to php8.1 now as 7.4 is on the way out soon

also, here are the docker examples. i'll probably include that in the docker repo too

All docker tags are php8.1 now

Thanks, I've been giving it a try but run into the issue in #90.
