How can I use different Redis connection with Laravel and phpredis, however, I followed the laravel documentation using-multiple-redis-connections but whenever I call this connection it always return the Redis default connection.

here's my Redis array in the database.php config file

'redis' => [



    'client' => env('REDIS_CLIENT', 'phpredis'),



    'options' => [

        'cluster' => env('REDIS_CLUSTER', 'redis'),

        'prefix'  => env('REDIS_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_').'_database_'),

    ],



    'default' => [

        'url'      => env('REDIS_URL'),

        'host'     => env('REDIS_HOST', '127.0.0.1'),

        'password' => env('REDIS_PASSWORD', null),

        'port'     => env('REDIS_PORT', '6379'),

        'database' => env('REDIS_DB', '0'),

    ],



    'cache' => [

        'url'      => env('REDIS_URL'),

        'host'     => env('REDIS_HOST', '127.0.0.1'),

        'password' => env('REDIS_PASSWORD', null),

        'port'     => env('REDIS_PORT', '6379'),

        'database' => env('REDIS_CACHE_DB', '1'),

    ],



    'redisCustomConnection' => [

        'url'      => env('REDIS_CUSTOM_URL'),

        'host'     => env('REDIS_CUSTOM_HOST', '127.0.0.1'),

        'password' => env('REDIS_CUSTOM_PASSWORD', null),

        'port'     => env('REDIS_CUSTOM_HOST', '6379'),

        'database' => env('REDIS_CUSTOM_DB', '0'),

    ],



],

here's .env file

REDIS_CUSTOM_URL=mycustom value

REDIS_CUSTOM_HOST=mycustom value

REDIS_CUSTOM_PASSWORD=mycustom value

REDIS_CUSTOM_HOST=mycustom value

REDIS_CUSTOM_DB=mycustom value

But it did not work it always return the default connection when I use

Redis::connection('redisCustomConnection');

My Answer:
[
'default' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
],

'cache' => [
'host' => env('REDIS_CACHE_HOST', '127.0.0.1'),
'password' => env('REDIS_CACHE_PASSWORD', null),
'port' => env('REDIS_CACHE_PORT', 6379),
'database' => 1,
],

'session' => [
'host' => env('REDIS_SESSION_HOST', '127.0.0.1'),
'password' => env('REDIS_SESSION_PASSWORD', null),
'port' => env('REDIS_SESSION_PORT', 6379),
'database' => 2,
],
]

In your code, you can specify which Redis connection to use by passing the connection name to the Redis facade or using the Redis::connection() method. Here's an example:

php
// Using the Redis facade
$value = Redis::connection('cache')->get('key');

// Using the Redis::connection() method
$redis = Redis::connection('session');
$value = $redis->get('key');


Make sure to update your .env file with the appropriate values for the Redis connections:


REDIS_CACHE_HOST=127.0.0.1
REDIS_CACHE_PASSWORD=null
REDIS_CACHE_PORT=6379

REDIS_SESSION_HOST=127.0.0.1
REDIS_SESSION_PASSWORD=null
REDIS_SESSION_PORT=6379


By specifying the connection name when using the Redis facade or the Redis::connection() method, you can access different Redis connections in your Laravel application.
