Php 致命错误：类'；Swift#U smtpTransport'；在中找不到

我正在尝试添加从我的网站后端向客户发送电子邮件的功能，并尝试使用swiftmailer来实现这一点。 不幸的是，我一直收到一条错误消息

Fatal error: Class 'Swift_smtpTransport' not found in /home/u312041955/public_html/cust/modules/customer/email.php on line 94

虽然在我看来，swiftmailer类没有被正确地包含，但它必须被包含，否则页面根本不会显示任何信息。 我使用的swiftmailer页面的代码如下

<?php require_once("include.php");
    //Required for swift mailer
    require_once (INCLUDE_URL.'/swift/lib/swift_required.php');
    if(!xml2php("customer")) {

    }

//print $sql ;
    $transport = Swift_smtpTransport::newInstance( "mx1.hostinger.co.uk" , 2525 )
    ->setUsername('noreply@example.co.uk')
    ->setPassword('******');
    $mailer = Swift_Mailer::newInstance($transport);
    //Create a message
    $message = Swift_Message::newInstance($email_subject)
      ->setFrom(array($email_from => $employee_details['EMPLOYEE_FIRST_NAME']))
     ->setTo(array($email_to => $cus_name))
     ->setBody($strip )
     ->addPart('Hello '.$cus_name , 'text/html')
     ->addPart($message_body, 'text/plain')
     ->attach(Swift_Attachment::fromPath($target_path));
     //Send the message
     $numSent = $mailer->send($message);
     //Display how many messages were sent
     echo "<script>alert('Email Information')</script>";
     echo "Sent %d messages\n", $numSent;
     exit(); 

    }
    ?>

简单地

$transport = Swift_MailTransport::newInstance()

因此，它不再使用SMTP。我收到一封成功发送的邮件通知，但由于某种原因，它会将其发送到发件人电子邮件地址，并被标记为垃圾邮件，因为它可能不是来自帐户，因此我想使用SMTP。 更新2：在阅读其他线程后，我发现

$transport = Swift_smtpTransport::newInstance( "mx1.hostinger.co.uk" , 2525 );

事实上应该是

$transport = Swift_SmtpTransport::newyInstance( "mx1.hostinger.co.uk" , 2525 )
;

这消除了类not found错误，但我现在得到了一个超时错误。我确信我使用了正确的邮件服务器详细信息，因为我从我的主机获得了它们。

非常感谢您的帮助

最终解决了这个问题

$transport = Swift_smtpTransport::newInstance( "mx1.hostinger.co.uk" , 2525 );

事实上应该是

$transport = Swift_SmtpTransport::newyInstance( "mx1.hostinger.co.uk" , 2525 );

然后，我的主机提供商不允许在我的计划中通过SMTP发送邮件。

答案与所问问题不符。

$transport = Swift_SmtpTransport::newyInstance( "mx1.hostinger.co.uk" , 2525 );
