PHPMailer发送消息,但返回CLIENT/SERVER对话框到浏览器

Question

所以我搜索了谷歌和Stackoverflow,我有点惊讶我找不到这个问题.

我正在使用XAMPP/localhost和PHPmailer使用我的Gmail电子邮件帐户向我的yahoo帐户发送电子邮件.一切都与发送和接收的电子邮件完美配合,包括样本附件.

问题是我的浏览器正在显示"发送成功"消息之前的场景处理后面每一步的SERVER/CLIENT对话框.

此处的示例输出:

2014-02-04 05:44:36 SERVER -> CLIENT: 220 mx.google.com
ESMTP xv2sm62192389pbb.39 - gsmtp
2014-02-04 05:44:36 CLIENT -> SERVER: EHLO localhost

2014-02-04 05:44:40 SERVER -> CLIENT: 221 2.0.0 closing connection xv2sm62192389pbb.39 - gsmtp 
Message has been sent

我设置了换行符以使其更具可读性,但它在屏幕上显示为一个长字符串.

这是代码.如何抑制此输出？

require_once "../phpmailer/class.phpmailer.php";

$mail = new \PHPMailer(true); 

$mail->IsSMTP();
$mail->Host       = "smtp.gmail.com";
$mail->Port       = 465;
$mail->SMTPDebug  = 2;
$mail->SMTPAuth   = true;
$mail->SMTPSecure = 'ssl';
$mail->Username   = "xxx@gmail.com";
$mail->Password   = "xxx";
$mail->SetFrom('xxx@gmail.com', 'Randy S');
$mail->WordWrap = 50;

$mail->AddAddress('xxx@yahoo.com', 'Randy');
$mail->Subject = 'PHPMailer Test Subject';
$mail->Body     = "Hi! \n\n This is my first e-mail sent through PHPMailer."; 
$mail->AddAttachment('upload/names.txt');      // attachment

if(!$mail->Send()){
echo "Mailer Error: " . $mail->ErrorInfo; 
} else {
echo "Message has been sent";
}

注释或删除此行或将其设置为0:

$mail->SMTPDebug  = 2; 

它用于显示错误和消息.

从PHPMailer站点:

$ mail-> SMTPDebug = 2; //启用SMTP调试信息(用于测试)
// 1 =错误和消息
// 2 =仅消息
