Deep Array Manipulation with Laravel’s replaceRecursive Method

Laravel’s replaceRecursive method offers a powerful solution for updating nested arrays while preserving unmodified values, particularly useful when working with complex configuration structures.

$collection = collect([
    'user' => [
        'name' => 'John',
        'settings' => [
            'theme' => 'dark',
            'notifications' => true,
        ]
    ]
]);

$updated = $collection->replaceRecursive([
    'user' => [
        'settings' => [
            'theme' => 'light'
        ]
    ]
]);

Let’s explore a practical example with a configurable dashboard system:

<?php

namespace AppServices;
use IlluminateSupportCollection;

class DashboardConfigurationService
{
    public function mergeUserPreferences(array $defaultConfig, array $userPreferences): array
    {
        return collect($defaultConfig)->replaceRecursive($userPreferences)->all();
    }

    public function getConfiguration(User $user): array
    {
        $defaultConfig = [
            'layout' => [
                'sidebar' => [
                    'position' => 'left',
                    'width' => 250,
                    'collapsed' => false
                ],
                'theme' => [
                    'mode' => 'light',
                    'color' => 'blue',
                    'font_size' => 14
                ],
                'widgets' => [
                    'weather' => true,
                    'calendar' => true,
                    'notifications' => true
                ]
            ]
        ];

        return $this->mergeUserPreferences(
            $defaultConfig,
            $user->dashboard_preferences ?? []
        );
    }
}

ReplaceRecursive provides an elegant way to handle deep array updates while maintaining unspecified values, perfect for managing configuration merges and preference systems.
