For mixed, this has been discussed several times, it's defined as the union of *all* value types (void aside), *including* null, according to its usage in phpDoc (and in Hack, which also has a nonnull type such that mixed is equivalent to ?nonnull, cf https://docs.hhvm.com/hack/types/nullable-types). For scalar, I already replied (https://externals.io/message/109715#109723) that it should not include null indeed (according to https://www.php.net/manual/en/language.types.intro.php and https://www.php.net/manual/en/function.is-scalar.php). -- Guilliam Xavier -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
