My recollection is that they have one or the other, but none with both =
side-by-side. (A very few have neither.)

/me nods

While I too have imagined that, my impression has been that consumers of =
1.x use $files unless & until they change their systems to use $uploads, =
at which point they switch over entirely to $uploads.  Given that, my =
concerns (such as they may have been) are soothed.

Noted.

Are there any others here who feel that the names $files and $uploads =
are "too confusing" (for whatever values of "confusing" you find =
appropriate) ?

Ah, my bad then.

I'm sorry, I'm still having trouble seeing what you're getting at. Do =
you mean something like this in the ServerRequest constructor?

    public function __construct(array $globals, ?string $content =3D =
null)
    {
        if (
            ($globals['_POST'] ?? null) =3D=3D=3D null
            &&
            strtolower($globals['_SERVER']['CONTENT_TYPE']) =3D=3D=3D =
'application/x-www-form-urlencoded'
        ) {
            if ($content =3D=3D=3D null) {
                $content =3D file_get_contents('php://input');
            }
            $globals['_POST'] =3D [];
            parse_str($content, $globals['_POST']);
        }

        // ...
    }

If so, it seems unnecessary for the goals of this RFC, even overkill.

If not, then I await correction.


> To play devil's advocate, does the [$content] property belong in the =
object at all? If it doesn't interact with any of the other properties =
(e.g. populating $post and $uploads based on form data), could "better =
syntax for getting raw request for global state" be a separate feature. =
Then again, maybe the ability to over-ride it in the constructor is =
enough to make it useful.

I continue to think it does belong there. Often enough, API developers =
will read php://input to decode JSON or XML they find there, so having =
it easily-available as $request->content is appealing.  To boot, the =
other content-related headers are present, so might as well have the =
content itself there too. And as you note, it's easy enough to pass in =
custom $content via the constructor, e.g. for testing.

* * *

I feel that if these are the discussion points, then we are close to =
exhausting the topic (even if we do not agree on everything). Thank you =
for your diligence and attention to detail!
