Eloquent sortBy - Specify asc or desc
提问by Lovelock
Trying sort my eloquent collection:
尝试整理我雄辩的收藏：
$collection->sortBy('field');
There is no information in Laravel 4's docs on how to choose descending or ascending for this sort method.
Laravel 4 的文档中没有关于如何为这种排序方法选择降序或升序的信息。
Is it possible?
是否可以？

To sort by ASC: Laravel Docs - sortBy()
按ASC排序：Laravel Docs - sortBy()
$collection->sortBy('field');
$collection->sortBy('field');
To sort by DESC: Laravel Docs - sortByDesc()
按DESC排序：Laravel Docs - sortByDesc()
$collection->sortByDesc('field');
$collection->sortByDesc('field');
