Then I would say that example is wrong, but people may find reason to
disagree. I'm basing my contention purely off what I see in php-src and the
documented behavior for those operators. To me I see no reason why this
behavior would be considered undefined. The ternary operator definitely has
some undefined behavior in terms of precedence since its interpreted as a
statement and not like other operators in expressions. To me post/pre
inc/dec are pretty well-defined.

I would say there is no harm in removing that comment from the
documentation.
