array_group_by

Packagist Build Status GitHub license, (*1)

A PHP function to group an array by a key or set of keys shared between all array members., (*2)

Installation

To get the latest version of array_group_by, simply require the project using Composer:, (*3)

``` shell $ composer require jakezatecky/array_group_by, (*4)


Need support for PHP 5.6? Then run the following:

``` shell
$ composer require jakezatecky/array_group_by:^1.1.0

If you do not want to use Composer, you can just require the src/array_group_by.php file., (*5)

Usage

To use array_group_by, simply pass an array with any number of keys to group by:, (*6)

``` php $records = [ [ 'state' => 'IN', 'city' => 'Indianapolis', 'object' => 'School bus', ], [ 'state' => 'IN', 'city' => 'Indianapolis', 'object' => 'Manhole', ], [ 'state' => 'IN', 'city' => 'Plainfield', 'object' => 'Basketball', ], [ 'state' => 'CA', 'city' => 'San Diego', 'object' => 'Light bulb', ], [ 'state' => 'CA', 'city' => 'Mountain View', 'object' => 'Space pen', ], ];, (*7)

$grouped = array_group_by($records, 'state', 'city');, (*8)


Example output:

``` text
Array
(
    [IN] => Array
        (
            [Indianapolis] => Array
                (
                    [0] => Array
                        (
                            [state] => IN
                            [city] => Indianapolis
                            [object] => School bus
                        )

                    [1] => Array
                        (
                            [state] => IN
                            [city] => Indianapolis
                            [object] => Manhole
                        )

                )

            [Plainfield] => Array
                (
                    [0] => Array
                        (
                            [state] => IN
                            [city] => Plainfield
                            [object] => Basketball
                        )

                )

        )

    [CA] => Array
        (
            [San Diego] => Array
                (
                    [0] => Array
                        (
                            [state] => CA
                            [city] => San Diego
                            [object] => Light bulb
                        )

                )

            [Mountain View] => Array
                (
                    [0] => Array
                        (
                            [state] => CA
                            [city] => Mountain View
                            [object] => Space pen
                        )

                )

        )
)

Using a Callback

If more complex grouping behavior is desired, you can also pass in a callback function to determine the group key:, (*9)

php $grouped = array_group_by($records, function ($row) { return $row->city; });, (*10)
