Laravel - Collections - Higher Order Messages

Collections also provide support for "higher order messages", which are short-cuts for performing common actions on collections. The collection methods that provide higher order messages are: average, avg, contains, each, every, filter, first, flatMap, groupBy, keyBy, map, max, min, partition, reject, skipUntil, skipWhile, some, sortBy, sortByDesc, sum, takeUntil, takeWhile, and unique.

Each higher order message can be accessed as a dynamic property on a collection instance. For instance, let's use the each higher order message to call a method on each object within a collection:

    use App\Models\User;
    $users = User::where('votes', '>', 500)->get();

Likewise, we can use the sum higher order message to gather the total number of "votes" for a collection of users:

    $users = User::where('group', 'Development')->get();
    return $users->sum->votes;
