Solution to garbled Chinese attachment names in emails sent by PHPMailer

$mail->AddAttachment($attach, $attach);

The attachment file name sent will be garbled, if not specified:

$mail->AddAttachment($attach, $attach);

The Chinese in the file name sent is gone and becomes ".txt".

Solution 1

Open class.phpmailer.php. Around line 1007, in the function AddAttachment, there is a sentence:

//$filename = basename($path);
if (false === strpos($path, '/'))
$filename = $this->EncodeHeader($path);
 else
$filename = $this->EncodeHeader(substr($path, strrpos($path, '/') + 1));

Solution 2

If you want to set the file name to Chinese, provide the Chinese name parameter (the second parameter) when calling AddAttachment. for example

$mail->AddAttachment('temp/2011/test.rar', 'test.rar');

Other problems: When sending Chinese emails, Chinese will appear Garbled code

The garbled characters are probably generated when the email title is converted into several small ones =?utf-8?B?...?=, and the Chinese may be accidentally truncated. Modify line 1185:

$maxlen = 75 - 7 - strlen($this->CharSet);

and change it to:

$maxlen = 75000 - 7 - strlen($this->CharSet);
