Nothing to add other than +1, however, didn't you already write those? https://wiki.php.net/rfc/nullable_types https://wiki.php.net/rfc/union_types
Or is this just an announcement that these will be finalized now? Btw. I am in favor of having the question mark as a suffix and not as a prefix because it is more readable and more natural to type. function fn(string? $str): bool?; Declare a function with the name fn that takes a string argument that is nullable which will return a bool or null. That is exactly how I would think about the above while writing and reading. :) -- Richard "Fleshgrinder" Fussenegger
