I use Collection:diff in combination with Collection::isEmpty for a reusable containsAll macro. When the supplied values contain an element that's not included in the collection to check against the result of diff won't be empty and therefore return false.
use Illuminate\Support\Collection;
Collection::macro('containsAll', function (...$values) {
return collect($values)->diff($this)->isEmpty();
});
$collection = collect(['three', 'nine', 'one', 'two']);
$collection->containsAll('one', 'two', 'three'); // true
$collection->containsAll('one', 'five', 'three'); // false
