Collections - 5.x

$collection = new Collection($people); $ladies = $collection->filter(function ($person, $key) { return $person->gender === 'female'; }); $guys = $collection->filter(function ($person, $key) { return $person->gender === 'male'; });

$items = [[1, 2, 3], [4, 5]]; $collection = new Collection($items); $new = $collection->unfold(); // $result contains [1, 2, 3, 4, 5]; $result = $new->toList();

잘되는구만
