PHP标题('Location:'。$ url)http1.0 vs http1.1 vs?

I'm doing some redirects using PHP, e.g.:

header('Location: '.$url);

But now I need to do some redirects with some other statuscodes.

Should I http1.0 or http1.1 for this. Or are we already at http2.0 or greater?

And are the status code the same for both?

So let's say I want to redirect using statuscode 404 (Not Found).

Can I just do:

header('HTTP/1.1 404 Not Found');
header('Location: '.$url);

Or is there a:

header('HTTP/2.0 404 Not Found');
header('Location: '.$url);

    There is not HTTP/2.0; HTTP/1.1 is the latest version.

    You can use the value of $_SERVER['SERVER_PROTOCOL'] to respond with the same protocol version:

    header($_SERVER['SERVER_PROTOCOL'].' 404 Not Found');
    

    At this point you should be aware that if the response is HTTP/1.0 the HTTP/1.1 header fields probably will be ignored.

    By the way: The Location header field is only defined for the status codes 201 and 3xx:

    For 201 (Created) responses, the Location is that of the new resource which was created by the request. For 3xx responses, the location SHOULD indicate the server's preferred URI for automatic redirection to the resource.
