count different values of a single column in Laravel

Question

I am working on Laravel framework. I have a table named 'traffic', contains data for visited users of my website, as like below:

id browser
1  Firefox
2  Firefox
3  Chrome
4  IE
5  Chrome

Now, I want to get the total number of each browser used in a single query. Here is my current query:

Traffic::selectRaw("count(case when browser = 'IE' then 1 end) as IE")
    ->selectRaw("count(case when browser = 'Firefox' then 1 end) as Firefox")
    ->selectRaw("count(case when browser = 'Chrome' then 1 end) as Chrome")
    ->groupBy('browser')
    ->first();

Which outputs similar to:

Row 1: IE=0, Firefox=0, Chrome=2
Row 2: IE=0, Firefox=2, Chrome=0
Row 3: IE=1, Firefox=0, Chrome=0

But, I want the result to be similar to:

Row 1: IE=1, Firefox=2, Chrome=2

Answer 1

Remove the GROUP BY logic to get a table-level summary:

Traffic::selectRaw("COUNT(CASE WHEN browser = 'IE' THEN 1 END) AS IE")
    ->selectRaw("COUNT(CASE WHEN browser = 'Firefox' THEN 1 END) AS Firefox")
    ->selectRaw("COUNT(CASE WHEN browser = 'Chrome' THEN 1 END) AS Chrome")
    ->get();
