Laravel Eloquent groupBy() 并且还返回每个组的计数 [英] Laravel Eloquent groupBy() AND also return count of each group

问题描述

我有一个表格，其中包含一列浏览器版本.我只是想从记录集中知道每种类型的浏览器有多少.所以，我需要得到这样的结果:Total Records: 10;Internet Explorer 8:2；铬 25:4；Firefox 20:4.(所有加起来为 10)

I have a table that contains, amongst other columns, a column of browser versions. And I simply want to know from the record-set, how many of each type of browser there are. So, I need to end up with something like this: Total Records: 10; Internet Explorer 8: 2; Chrome 25: 4; Firefox 20: 4. (All adding up to 10)

这是我的两便士:

$user_info = Usermeta::groupBy('browser')->get();

当然，这只是包含 3 个浏览器，而不是每个浏览器的数量.我该怎么做?

Of course that just contains the 3 browsers and not the number of each. How can I do this?

推荐答案

这对我有用:

$user_info = DB::table('usermetas')
                 ->select('browser', DB::raw('count(*) as total'))
                 ->groupBy('browser')
                 ->get();
