我尝试使用 phpmailer 发送电子邮件，但在发送电子邮件后，即使邮件已成功发送，我也会收到大量数据，谁能帮助我知道为什么会发生这种情况以及我如何才能停止看到此消息

这是我为发送邮件所做的

$mail = new PHPMailer;

$mail->SMTPDebug = 3;                                      // Enable verbose debug output

$mail->isSMTP();   
$mail->SMTPDebug = 1;                                    // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';                         // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                                // Enable SMTP authentication
$mail->Username = 'myemail@gmail.com';         // SMTP username
$mail->Password = 'myphonenumber';                      // SMTP password
$mail->SMTPSecure = 'tls';                          // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;  
$mail->SetFrom('example@testrun.com','yahoo');
$mail->addAddress('example@test.com', 'User'); // Add a recipient
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
   echo 'Message could not be sent.';
   echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

发送电子邮件后我得到的是

【解决方案1】：

删除这一行：

$mail->SMTPDebug = 1;

或将值更改为 0 或 3

0 = 没有
1 = 错误和消息
2 = 仅消息
3 = 没有

不客气，下次检查谷歌...它就在那里;）

【解决方案2】：

改变

$mail->SMTPDebug = 3;

到

$mail->SMTPDebug = 0;
