Can you provide sample code to integrate Redis with Laravel

Install Redis and Predis

First, install the Redis server on your system and the Predis library in your Laravel project:

bash
composer require predis/predis

Configure Redis Connection

In your `config/database.php` file, configure the Redis connection details:

php
'redis' => [
    'client' => env('REDIS_CLIENT', 'predis'),
    'default' => [
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD', null),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
    ],
],

Use Redis Facade

In your Laravel code, you can use the `Redis` facade to interact with Redis. For example, to set and retrieve a key-value pair:

php
use Illuminate\Support\Facades\Redis;

Redis::set('name', 'Taylor');
$value = Redis::get('name');

You can call any Redis command on the `Redis` facade and it will be passed directly to Redis[1][2][3].

Caching with Redis

To use Redis as a cache driver in Laravel, update the `CACHE_DRIVER` environment variable to `redis` in your `.env` file[4].

Then in your code, you can use the `Cache` facade to store and retrieve cached values:

php
use Illuminate\Support\Facades\Cache;

Cache::put('key', 'value', 60); // cache for 60 seconds
$value = Cache::get('key');

Pub/Sub with Redis

Laravel provides a convenient interface to the Redis publish and subscribe commands using the `Redis` facade[2][3]:

php
Redis::subscribe(['messages'], function($message) {
    echo $message;
});

Redis::publish('messages', json_encode(['foo' => 'bar']));

This allows you to build real-time features like chat, notifications, and more.

By leveraging Redis's speed and data structures, you can significantly boost the performance and scalability of your Laravel application[1][4].
