我如何与Laravel合作？

Question

我的stock_comments表格如下

id|user_id|stock_id|comment|
1 |   8   |    6   | stock comment one
2 |   8   |    6   | stock comment two
3 |   8   |    6   | stock comment three
4 |   8   |    6   | stock comment four
5 |   9   |    7   | stock comment one
6 |   9   |    7   | stock comment two

我的控制器如下

 $stock_comments = StockComment::where('stock_id' , $id)->where('comment_type' , 'recommendation')->groupBy('current_id')->orderBy('id', 'desc')->get();

如何根据个人user_id保留数组注释？ 请帮帮我。
