4,php Test Code

Create Channel
$this->_channel = new Amqpchannel ($this->_conn);
Creating Exchange Switches
$this->_exchange = new Amqpexchange ($this->_channel);
$this->_exchange->setname ($this->exchange_name);//Create Name
$this->_exchange->settype (Amqp_ex_type_direct);
$this->_exchange->setflags (amqp_durable | Amqp_autodelete);
$this->_exchange->declare ();

creating queues
$this->_queue = new Amqpqueue ($this->_channel);
Set the queue name if it does not exist add
$this->_queue->setname ($this->queue_name);
$this->_queue->setflags (amqp_durable | Amqp_autodelete);
echo "Queue status:". $this->_queue->declare ();

echo "<br/>";
Echo ' queue bind: '. $this->_queue->bind ($this->exchange_name, $this->route_key);//bind your queue to Routingkey

}

/**
*
* Add information to the queue
*/
Public Function Setrabbitmqinfo ()

Post message
$message = Json_encode (Array (' Hello world! ', ' php ', ' C + + '));
$this->_channel->starttransaction ();
echo "Send:". $this->_exchange->publish ($message, $this->route_key); Send your message through the development Routingkey

/**

if ($messages) {
echo "<pre>";
Print_r (Json_decode ($messages->getbody (), true). " \ n ";

Disconnect
$this->_conn->disconnect ();
}
}

<?php
Set_time_limit (0);
Include_once (' rabbitmq.inc.php ');

$ra = new RABBITMQ ();
$ra->setrabbitmqinfo ();
$ra->getrabbitmqinfo ();

The results are as follows
[root@vpn208 ~]# php test.php
Queue status:0<br/>queue bind:1<br/>send:1<pre>array
(
[0] => Hello world!
[1] => PHP
[2] => C + +
