Haven't seen you in a while, great video!

Thanks for sharing the native version!

Love the video, thanks Matt! I tend to like using $carry[$name] ??= [] & $carry[$name][$key] ??= 0 just to clean things up, but obviously that's a personal preference. :)

Great video! I just noticed the typo in the description :)

First before making code look more elegant I'll use $name = isset( $item['name'] ) ? $item['name'] : null; if ( is_null( $name ) ) continue; or do something else, but assuming 'name' index is always present is ask for a NOTICE

It's a couple of years since I've used PHP, but can't you simply do `$carry[$name][$key] += $val` (i.e. without initialising it) relying on it adding $val to nothing or maybe `$carry[$name][$key] = ($carry[$name][$key] ?: 0) + $val` to be a little safer?

Hi @Matt

Cool explanation after edit video, suggesttion by Titan.
it could put more value to video if you add Big (O) value of your function. or in simple word it's space 🚀 and time ⌛ complexity.

The non Laravel version is easier to read as per usual
