未定義のメソッドを呼び出す

Question

私は最新のバージョンog php-amqpをインストールしましたが、私は方法channel()を使用しているようです。これは、コード

<?php 
ini_set('display_errors', 1); 
ini_set('display_startup_errors', 1); 
error_reporting(E_ALL); 


require_once __DIR__.'/vendor/autoload.php'; 

use PhpAmqpLib\Connection\AMQPStreamConnection; 
use PhpAmqpLib\Message\AMQPMessage; 


$cnn = new AMQPConnection(); 

// set the login details 
$cnn->setLogin('guest'); 
$cnn->setPassword('guest'); 

if ($cnn->connect()) { 
    echo "Established a connection to the broker"; 
} 
else { 
    echo "Cannot connect to the broker"; 
} 

$channel = $cnn->channel(); 

$channel->queue_declare('email_queue', false, false, false, false); 

$data = 'lorem ipsum'; 

$msg = new AMQPMessage($data, array('delivery_mode' => 2)); 
$channel->basic_publish($msg, '', 'email_queue'); 

?> 

であり、これは私が、私はそれをこのように解決し

Established a connection to the broker Fatal error: Uncaught Error: Call to undefined method AMQPConnection::channel() in /var/www/html/rabbit.php:26 Stack trace: #0 {main} thrown in /var/www/html/rabbit.php on line 26
