redis connection inside infinite loop

Question

I'm creating a redis connection using phpredis client

$redis = new Redis();
$redis->pconnect(loclahost, 6336, 2) ;
$redis->select(15);

Now I used the $redis object inside an infinite loop.

while(true){
   ///using redis connection object.
}

Around 54 such individual processes were running but once or twice in a day I get an error like "read error on connection".

Please help me to fix it.

I would think something like this would work. NOTE I have not tested this, and I have not written PHP in a pretty long time.

function redisConnection() {
    try {
        $redis = new Redis()
        $redis->pconnect(localhost, 6336, 2);
        $redis->select(15);
        $redis->ping();
        return $redis;
    } catch (Exception $e) {
        throw new Exception("Can not connect: " . $e->getMessage());
    }
}

$redis = redisConnection();
while (true) {
    try {
        $redis->ping();
    } catch {
        $redis = redisConnection();
    }
    // Rest of code
}
