What

If a nested array is passed into a Laravel Collection, by default these will be threaded as normal arrays.

However, that's not always the ideal case and it would be nice if we could have nested collections in a cleaner way.

This is where this macro comes in handy.

Setup

Register this macro for example on the boot method of your app\Providers\AppServiceProvider.php file:

\Illuminate\Support\Collection::macro('recursive', function () {
    return $this->map(function ($value) {
        if (is_array($value) || is_object($value)) {
            return collect($value)->recursive();
        }

        return $value;
    });
});

How

Usage is quite simple:

$data = [
    [
        'name' => 'John Doe',
        'emails' => [
            'john@doe.com',
            'john.doe@example.com',
        ],
        'contacts' => [
            [
                'name' => 'Richard Tea',
                'emails' => [
                    'richard.tea@example.com',
                ],
            ],
            [
                'name' => 'Fergus Douchebag', // Ya, this was randomly generated for me :)
                'emails' => [
                    'fergus@douchebag.com',
                ],
            ],
        ],
    ],
];

$collection = collect($data)->recursive();
