[rabbitmq-discuss] Doubts in bindings

Tue Feb 25 09:41:34 GMT 2014

Hi,

I think the OP is asking about the first line of the output:

"        exchange        q1      queue   q1      []    ----> what is this ?"

That's the default or "anon" exchange. Every queue is automatically
bound to that exchange using the queue name as routing key.

So you could publish a message to a queue like this:

$channel->basic_publish($msg, "", $queue_name);

The empty string there is the name of the anon exchange, that's why
the output of list_bindings shows a blank where the exchange name
should have appeared.

Regards,

Alvaro
