Why you declare const inside a function?

Besides that, even if the const worked, the function would fail anyway it would never match.

Thanks. just solved it. but I saw community solutions, this question has not many different answers one of few different I remember was return array_flip(COLORS)[$color); Well I just forgot I can't create a constant either way: const or define() inside a function() in PHP. This exercise blown my mind for like a day now, it's a shame for me and I will surely remember it until I do something bit dumb silly shit than this LoL. I have a doubt. the same guy with that above solution, the return statment, made an 'array', something like const COLORS = [0 => "black", 1=> "brown", ] .. elements and so on, the list already mentioned. I thought array/associated array keys must be strings like ["0" => "black"]. anyways, forgive me. but should he just write an array? like ["black", "brown"] what's the point? array indexes starts with 0 anyway!

You can specify the position, it could be numeric or string, so in a numeric it could be for something like this [0 => 'asd', 5 => 'ddd'], when the numbers are not linear, but if you are going to just do it incremental then is not necesary.
