Laravel Eloquent groupBy() and Return Count of Each Group

Are you wondering how to use Laravel's Eloquent groupBy() function to group your data based on a column, and also retrieve the count of each group? Look no further! In this blog post, I'll show you a simple and easy solution to achieve that.

The Problem

Let's say you have a table that includes a column for browser versions, and you want to know the number of records for each type of browser. Your desired result might look something like this:

Total Records: 10

• Internet Explorer 8: 2

• Chrome 25: 4

• Firefox 20: 4

The Solution

To accomplish this, you can utilize Laravel's groupBy() function along with the count() function to get the desired result. Here's how:

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

Let's break this down:

• We start by calling the groupBy('browser') function on the Usermeta model, which groups the records based on the 'browser' column.

• Next, we use the select() function to specify the columns we want to retrieve. In this case, we select the 'browser' column and use the DB::raw() method along with count(*) to calculate the count for each group. We also give this count a name 'total' using the as keyword.

• Finally, we call the get() function to execute the query and retrieve the results.

Now, when you access the $user_info variable, you will have an array of objects with each object containing the browser name ('browser') and the count ('total') for that browser.

Conclusion

By using Laravel's groupBy() function in combination with the count() function and making use of the select() method, you can easily group your data based on a column and retrieve the count of each group. This provides you with a simple and efficient way to solve the problem at hand.
