it's not the best of both worlds though, splat should only be used on something where you're basically doing the same thing to a bunch of things. like add(1,2,

it's not the best of both worlds though, splat should only be used on something where you're basically doing the same thing to a bunch of things. like add(1,2,3,4,5) -> function add(...$nums){ $count = 0; foreach($nums as $num) { $count += $num; } } If you know what arguments you're getting, then the more sound way would be just use an associative array, but either way you really don't get great type checking. This is a much better solution.
