php - How to check whether the Redis server is running

Question

How to check whether the Redis server is running?

If it's not running, I want to fallback to using the database.

I'm using the FuelPHP framework, so I'm open to a solution based on this, or just standard PHP.

What you can do is try to get an instance (Redis::instance()) and work with it like this:

try
{
    $redis = Redis::instance();
    // Do something with Redis.
}
catch(RedisException $e)
{
    // Fall back to other db usage.
}

But preferably you'd know whether redis is running or not. This is just the way to detect it on the fly.
