Pass array as cache key

[jxxe]

TanStack Query allows you to pass an array of stringable items as the key for a cache.

It's a minor thing, but it feels nicer than concatenating multiple items. In Laravel, it could look like this:

cache()->remember(['event', $id], now()->addHour(), function() {
    // ...
});

...which would be equivalent to this:

cache()->remember('event'.$id, now()->addHour(), function() {
    // ...
});

Cache keys are for computers, not humans, and this takes away some of the (admittedly minor) pressure of naming them.

As a workaround, you can use implode?

Whilst I can appreciate the need for this where the cache index id is a combination of several different items, I am not sure that the relatively simple example provided does justice to this need. I would therefore propose:

cache()->remember(['promotion', $country_id, $year, $month], now()->addMonth(), function() {
    // ...
});

instead of:

cache()->remember('promotion-' . $country_id .  '-' .  $year . '-' . $month, now()->addMonth(), function() {
    // ...
});

or:

cache()->remember('-' . implode(['promotion', $country_id, $year, $month]), now()->addMonth(), function() {
    // ...
});
