I'm missing a thing here when we talk about "your code". I mean on
our
site we have third party libraries. They can typically have a release
schedule on a couple of releases each year. So all code is not up to
us to change. So how does this proposal adress that scenario when it's
not up to us to do the necessary changes? Is it e.g. a blocker to
upgrade to PHP 8.1 with exceptions vs warnings until the library
is updated?
As a side note I'm at the moment migrating our test site to PHP 8 and
the two most prominent hickups are located in a third party library:
"Undefined array key" and "Attempt to read property "value" on null"
which are warnings. Not sure how it would have been with these as
exceptions, e.g. would the test site stop running and thereby stop
testing of other parts.
And as I have said earlier, I do like exceptions! It's the migration
aspect I'm wondering about...

This is a valid concern. I have thought about it for a while and I
think that we should handle this the same way we did with PDO error
mode change. We don't do anything special.
I really don't see a way that we could make a smoother upgrading
experience. For users that avail of old libraries the onus is on them
to check the library's compatibility with the new PHP version.
Ideally, the change should have been made in PHP 8.0 where it would be
more justifiable to change a default setting.
The good thing about mysqli error reporting compared to PDO is that
the setting is global. If the library you are using is abandoned or
you can't wait for the library to be updated then you can set the
error reporting level in your own code. The only problem comes when
you want to mix both modes in the same code, but that is a huge code
smell anyway. This means that this change is not a blocker for the
upgrade.
I think the proposal is good to be implemented in PHP 8.1 as it is
now. But if anyone thinks otherwise or has any ideas on how to improve
I would gladly take it into consideration. If there is any way that we
could make the migration smoother then it would be great.

Yes, this proposal would probably have been close to a no-brainer in
PHP 8.0.
I think the RFC would benefit on expanding on some of the key issues
that has been discussed, e.g. the clarification above about migration
aspects.
