Why is PHP mailer printing mimeheader to screen after send?

问题

Here is the problem, I have just implemented PHPMailer and it is printing the Mime Header to the screen after the email is sent. I am using the latest PHPMailer code listed on GITHUB, and I have gone through virtually everything but cant find any reason why this is printing to the screen. Let me know if you need anymore information. I cant seem to think of anything else. See below:

Here is the implementing code:

require("class.phpmailer.php");

$mail = new PHPMailer;

$mail->From = 'xxxxx@xxxxxxx.com';
$mail->FromName = 'xxxxxxx xxxxx';
$mail->addAddress($email, $fname);                  
$mail->addReplyTo('', '');
$mail->IsSMTP();                            
$mail->SMTPDebug = 1;                       
$mail->SMTPAuth = true;                         
$mail->SMTPSecure = 'ssl';                      
$mail->Host = "smtpout.secureserver.net ";
$mail->Port = 465;                          
$mail->Username = "xxxxx@xxxxxxx.com";
$mail->Password = "password";
$mail->WordWrap = 50;                                       
$mail->isHTML(true);                                        

$mail->Subject = 'xxxxxxx.com Confirmation';
$mail->Body    = "This is the text body of the message, it is printed here.  blah blah blah";
$mail->AltBody = "This is the alternate text body for non-html email that may or may no be reading this.<br />This is also the text body";

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

回答1:

You need set

$mail->SMTPDebug = false;

回答2:

Personally, I expected SMTPDebug to write to the error_log rather than echo to the screen.

Add this to your PHPMailer configuration to enable this behavior:

$mail->Debugoutput = 'error_log';

Thankfully this is supported, just not the default.
