To reduce nested condition, using the ?: operator to do that.
Using the ?? syntax to reduce conditions.
Using the error Exception first to enhance condition logic.

What do you mean about this comment?

I don't like the null coalesce operator here, as it also allows for undefined variable without notice. This operator is equivalent to isset($values) ? $values : [], not strictly equivalent to the original code.

This condition is not related to the null coalesce operator.

I think this change is proper approach.

This change brings no value.

This approach is about error exception first.

It's about change the order of conditions.

I got that, but what's the point? Please don't spent time on nitpick like this :)

Ok. I will not spend time about this change.

You can keep this change alone.

How about reverting this due to your previous comment.

This is an isset($x) ? $x : null, so conceptually equivalent to $x ?? null. I can accept this change.
