Changes to finfo and imap functions

The chagelog for PHP 8.1 lists the two following changes:

• Fileinfo:
  . The fileinfo functions now accept and return, respectively, finfo objects
  instead of resources.

• IMAP:
  . The IMAP functions now accept and return, respectively, IMAPConnection objects
  instead of resources.

I suppose these changes are part of the move away from "resources everywhere" ? I was wondering whether these function will still accept resource objects in PHP 8, or if support for them is completely removed.

I tried searching externals.io http://externals.io/ for a previous discussion but could only find https://externals.io/message/111297#111298 https://externals.io/message/111297#111298

Yes, these changes fall under the general resource to object conversion
(which is IMO generally a very good move), and the respective resources
are completely removed. However, it seems that the incompatibility is
not only wrt. is_resource() checks, which can easily be resolved (and
may not be an issue for some code bases), but also regarding conversion
to int. It might be sensible to implement cast_object handlers for
those classes, which may be deprecated.

The SSH2 extension would need particular attention in this regard, since
it deliberately uses resource to int/string conversion for its wrappers,
and even looks up the resources from the regular_list[1].
