Hi! So, PHP has the '+' array operator, which forms the union of arrays, but it does so by key. What I'm looking for is a function that forms the union of arrays based on value. Currently, I use code like the following: array_unique(array_merge($array1, $array2, $array3)); This is useful to me because I tend to program using functional programming principles. Just want to make sure I'm not missing a core function that already does this. If there's not a core function, I might just build an array_union extension because the functionality is so common in my codebases.
