Hi internals, PHP currently has an incorrect right-associative ternary operator. In https://wiki.php.net/rfc/ternary_associativity the use of nested ternaries was deprecated, and was supposed to become an error in PHP 8.0.
Concurrently with that proposal https://wiki.php.net/rfc/concatenation_precedence made a very similar change to the concatenation operator precedence. The difference here is that this throws a deprecation notice in PHP 7.4 (same), but changes the behavior in PHP 8.0 (rather than making it an error). This is a pretty nonsensical outcome, in that the same type of change is implemented in two different ways. I think it would be good to handle the ternary change the same way as the concatenation change, i.e. make ternaries use the correct left-associative behavior in PHP 8.0, rather than throwing an error. Any thoughts on that? Regards, Nikita
