What RabbitMQ can do for you (phpnw14 Uncon)

This document discusses RabbitMQ, an open source message broker. It describes how RabbitMQ allows applications to communicate asynchronously by sending and receiving messages through queues. It provides examples of different RabbitMQ exchange types including fanout, direct, and topic exchanges to illustrate how messages can be routed from producers to consumers. The examples are implemented in PHP using the AMQP library to demonstrate basic usage of RabbitMQ for message queuing and scaling applications.
![fanout/consumer.php
$q = $channel->queue_declare(
'', // Lets RabbitMQ pick a name for queue
false, false, false,
true // Delete this queue
);
$queue_name = $q[0];
$channel->exchange_declare(
'test_exchange', 'fanout', false, false, false);
$channel->queue_bind($queue_name, 'test_exchange');](https://image.slidesharecdn.com/141004-whatrabbitmqcandoforyouphpnw14uncon1-141005080716-conversion-gate02/85/What-RabbitMQ-can-do-for-you-phpnw14-Uncon-24-320.jpg)

$q = $channel->queue_declare('', false, false, false, true);

$channel->exchange_declare(

// Bind for each routing key we want (BINDING KEY)
