Unfortunately there is an ugly special case if there is only a single array, which makes this not actually usable in practice, unless you know that there are at least two arrays. As such, accepting zero arrays wouldn't be very useful unless we also want to fix that issue (PHP 8 maybe?) > array_diff() & friends array_intersect() & friends These look like good candidates for allowing a single arg.
