我安装了rabbitmq和php的amqp扩展，但是不知道怎么使用，我在网上搜了教程，但是不是太懂，
这是send.php文件，

<code>$conf=[
  'host'=>'localhost',
  'port'=>'5672',
  'login'=>'guest',
  'password'=>'guest',
  'vhost'=>'/'
];
$connect=new \AMQPConnection($conf);
if(!$connect->connect()){
  die('connetc error');
}
$message = "TEST MESSAGE! 测试消息！";
$channel=new AMQPChannel($connect);
$exchange=new AMQPExchange($channel);
$exchange->setName('zblExchange');
$queue = new AMQPQueue($channel);
$queue->setName('zblQueue');
for($i=0; $ipublish($message, 'zblQueue')."\n";
}
//$channel->commitTransaction(); //提交事务

$connect->disconnect();
</code>

这是receive.php文件

<code>$conf=[
  'host'=>'localhost',
  'port'=>'5672',
  'login'=>'guest',
  'password'=>'guest',
  'vhost'=>'/'
];
$connect=new AMQPConnection($conf);
if(!$connect->connect()){
  die('connetc error');
}
$channel=new AMQPChannel($connect);
$exchange=new AMQPExchange($channel);
$exchange->setName('zblExchange');
$exchange->setType(AMQP_EX_TYPE_DIRECT);
//echo "Exchange Status:".$exchange->declare()."\n";

$queue = new AMQPQueue($channel);
$queue->setName('zblQueue');
$queue->setFlags(AMQP_DURABLE); //持久化
echo "Message Total:".$queue->declare()."\n";
echo 'Queue Bind: '.$queue->bind('zblExchange', 'zblQueue')."\n";
echo "Message:\n";
//while(True){
  $queue->consume('processMessage');
  //echo'hello';
  //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答
//}

$connect->disconnect();
function processMessage($envelope, $queue) {
  $msg = $envelope->getBody();
  echo $msg."\n"; //处理消息
  $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答
}

使用浏览器先访问send.php没什么问题,再访问receive.php是504 gateway timeout，使用命令行访问send.php的时候出现致命错误AMQPConnection类找不到，我不知道是怎么回事，使用php -m的时候找不到安装的amqp扩展，但是使用phpinfo通过浏览器访问的时候显示的是amqp是加载的，使用环境是centos 7，nginx 1.6.3，php 5.6.9，请问我这里到底是哪里出了问题？
