Laravel Group by Example

Laravel Group by Example

Laravel’s groupBy method is a powerful feature that allows developers to efficiently group query results based on a specific column or attribute. In this tutorial, you will learn how to use group by with different purpose in laravel.

As well as you learn how to use laravel group with raw, laravel group by multiple, laravel group by date, laravel group by sum, laravel group by month and laravel collection group by count.

Sometimes, you may confuse when use group by with laravel eloquent queries. So this tutorial will guide you how to use laravel group by with different purpose with example.

Laravel Group By Examples

Here are following examples of laravel group by eloquent method:

  • 1: Laravel GroupBy with Collection Example
  • 2: Laravel Collection Group By Preserve Key
  • 3: Laravel Collection Group By with Multiple Columns
  • 4: Laravel Collection Group By with Date
  • 5: Laravel Collection Group By with Count
  • 6: Laravel Collection Group By with Sum

1: Laravel GroupBy with Collection Example

public function index()
{
    $collection = collect([
            'first' => ['id'=>1, 'name'=>'Rahul', 'city' => 'Mumbai', 'country' => 'India'],
            'second' => ['id'=>2, 'name'=>'Sumit', 'city' => 'New York', 'country' => 'US'],
            'third' => ['id'=>3, 'name'=>'Ronak', 'city' => 'Gujarat', 'country' => 'India'],
            'fourth' => ['id'=>4, 'name'=>'Harish', 'city' => 'New York', 'country' => 'US'],
        ]);
  
    $grouped = $collection->groupBy('country');
      
    dd($grouped);
}

Result:

Illuminate\Support\Collection Object
(
    [items:protected] => Array
        (
            [India] => Illuminate\Support\Collection Object
                (
                    [items:protected] => Array
                        (
                            [0] => Array
                                (
                                    [id] => 1
                                    [name] => Rahul
                                    [city] => Mumbai
                                    [country] => India
                                )
                            [1] => Array
                                (
                                    [id] => 3
                                    [name] => Sumit
                                    [city] => Gujarat
                                    [country] => India
                                )
                        )
                )
            [US] => Illuminate\Support\Collection Object
                (
                    [items:protected] => Array
                        (
                            [0] => Array
                                (
                                    [id] => 2
                                    [name] => Ronak
                                    [city] => New York
                                    [country] => US
                                )
                            [1] => Array
                                (
                                    [id] => 4
                                    [name] => Harish
                                    [city] => New York
                                    [country] => US
                                )
                        )
                )
        )
)

2: Laravel Collection Group By Preserve Key

here, we will use same example as above but we will pass preserve key as true. so you can compare both output and see. there is difference is “key”, here will be key name same.

$collection->groupBy('Key_Name', $preserve_key);
public function index()
{
    $collection = collect([
            'first' => ['id'=>1, 'name'=>'Rahul', 'city' => 'Mumbai', 'country' => 'India'],
            'second' => ['id'=>2, 'name'=>'Sumit', 'city' => 'New York', 'country' => 'US'],
            'third' => ['id'=>3, 'name'=>'Ronak', 'city' => 'Gujarat', 'country' => 'India'],
            'fourth' => ['id'=>4, 'name'=>'Harish', 'city' => 'New York', 'country' => 'US'],
        ]);
  
    $grouped = $collection->groupBy('country', True);
      
    dd($grouped);
}

Result:

Illuminate\Support\Collection Object
(
    [items:protected] => Array
        (
            [India] => Illuminate\Support\Collection Object
                (
                    [items:protected] => Array
                        (
                            [first] => Array
                                (
                                    [id] => 1
                                    [name] => Rahul
                                    [city] => Mumbai
                                    [country] => India
                                )
                            [third] => Array
                                (
                                    [id] => 3
                                    [name] => Ronak
                                    [city] => Gujarat
                                    [country] => India
                                )
                        )
                )
            [US] => Illuminate\Support\Collection Object
                (
                    [items:protected] => Array
                        (

                                    [name] => Sumit
                                    [city] => New York
                                    [country] => US
                                )
                            [fourth] => Array
                                (
                                    [id] => 4
                                    [name] => Harish
                                    [city] => New York
                                    [country] => US
                                )
                        )

6: Laravel Collection Group By with Sum

public function index()
