Publish event missing

[Deisss]

On PubSubContext.php :

Please add the following command :

After class start :
const PUBLISH = 'publish';

Somewhere :
/**
* Publish an event to the specified channel
* @param mixed $arg,... One or more channel names.
/
public function publish(/ arguments */){
$this->writeCommand(self::PUBLISH, func_get_args());
}

Based on code showed for subscribe & co. Tested & work ;)

Are you sure it works for you? The problem is that you can't send PUBLISH to a channel using the same connection being used to receive messages because Redis internally marks that connection in a special state, and if you try do do that Redis will reply with -ERR only (P)SUBSCRIBE / (P)UNSUBSCRIBE / QUIT allowed in this context.

I've no idea, i did this stuff because i'm using only publish from PHP.

I use publish from PHP to send an event recieved by Node.JS and Node.JS publish a real time modifcation to all client (socket.io).

So I don't use subscribe from PHP, but from Node.JS, there is so 2 connection, and in this way it works great !

So maybe you should create a specific cas which refuse to use both with same connection...

If you don't subscribe to any channel from PHP then you don't need the Predis\PubSub\PubSubContext class since it implements an abstraction for a pubsub consumer loop (and this is why that class implements only the commands allowed in a pub/sub context). Just use PUBLISH with the plain client instance:

$client = new Predis\Client();
$client->publish('my:channel', 'message payload');

FYI It might be worth putting that last point somewhere near the pubsub subscribe docs as I've just spent a while trying to figure out the same thing.

@jmoz sure, will do that soon since we are starting with writing a descriptive documentation of the whole library.
