本文介绍了一个使用PHP结合RabbitMQ实现的消息队列系统，通过两个示例脚本publisher.php和consumer.php展示了如何发布消息到RabbitMQ交换机以及如何消费这些消息并将其存入数据库。

分为消息发布者（publisher.php）和消费者（consumer.php）

publisher.php

<?php
$conn_args = array(
    'host' => '127.0.0.1',
    'port' => '5672',
    'login' => 'guest',
    'password' => 'guest',
    'vhost'=>'/'
);

//创建连接和channel
$conn = new AMQPConnection($conn_args);
if (!$conn->connect()) {
    die("Cannot connect to the broker!\n");
}
$channel = new AMQPChannel($conn);

//创建交换机
$e_name = 'e_linvo'; //交换机名
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
$ex->setFlags(AMQP_DURABLE); //持久化
$ex->declare();

$sStr = 'abcdefg';
//echo "Send Message:".$ex->publish("TEST MESSAGE，key_1 by xust" . date('H:i:s', time()), 'key_1')."\n";
//echo "Send Message:".$ex->publish("TEST MESSAGE，key_2 by xust" . date('H:i:s', time()), 'key_2')."\n";
$ex->publish($sStr, 'key_1');
echo "end\n";

consumer.php

<?php
$conn_args = array(
    'host' => '127.0.0.1',
    'port' => '5672',
    'login' => 'guest',
    'password' => 'guest',
    'vhost'=>'/'
);

$e_name = 'e_linvo'; //交换机名
$q_name = 'q_linvo'; //队列名
$k_route = 'key_2'; //路由key

//创建连接和channel
$conn = new AMQPConnection($conn_args);
if (!$conn->connect()) {
    die("Cannot connect to the broker!\n");
}
$channel = new AMQPChannel($conn);

//创建交换机
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
$ex->setFlags(AMQP_DURABLE); //持久化
$ex->declare();

//创建队列
$q = new AMQPQueue($channel);
$q->setName($q_name);
$q->setFlags(AMQP_DURABLE); //持久化
$q->declare();     //最好队列object在这里declare()下，否则如果是新的queue会报错

//绑定交换机与队列，并指定路由键，可以多个路由键
$q->bind($e_name, 'key_1');
//$q->bind($e_name, 'key_33');

//阻塞模式接收消息
echo "Message:\n";
$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答

$conn->disconnect();

/**
 * 消费回调函数
 * 处理消息
 */
function processMessage($envelope, $queue) {
    var_dump($envelope->getRoutingKey());
    $msg = $envelope->getBody();
    mysql_insert($msg);

}

function mysql_insert($json){
   $pdo = new PDO("mysql:host=localhost;dbname=testdb","root","111111",array(PDO::ATTR_PERSISTENT => true) );
   $sql = "insert into t_test(sJson) values ('{$json}')";
   echo $sql."\n";
    if ($pdo->exec($sql)){
        echo "insert success\n";
    } else {
        echo "error\n";
    }
}

执行这两个文件，没问题的话可以在数据库中看到新增的数据
