Some methods on Laravel cache, dont have a direct way to set a ttl, like incremet. Or you do just an put method without any ttl. Well, on large applications, will be a problem. A huge DB with old unused values.

Removing old items on Redis

php artisan cache:clear-old-items

Command code

use Illuminate\Console\Command;
use Illuminate\Support\Facades\Redis;

class CacheClearOldItemsCommand extends Command
{
    protected $signature = 'cache:clear-old-items {max_days_ttl=10}';
    protected $description = 'Remove old created elements on redis cache.';

    public function handle(): void
    {
        $redis = Redis::connection();
        $max_ttl = $this->argument('max_days_ttl') * 24 * 3600;

        foreach($redis->keys('*') as $item_key) {
            $idle_time = $redis->object('idletime', $item_key);
            if ($idle_time < $max_ttl)
            {
                continue;
            }
            $redis->del($item_key);
            // $redis->unlink($item_key);   // Redis >= 4.0.0
            $this->line(
                str_pad($item_key, 40)
                .' | '.str_pad(now()->subSeconds($idle_time)->diffForHumans(), 20)
                .' | deleted.'
            );
        }
    }
}

Disclaimer: this command works with phpredis as Laravel database driver.
