我正在使用php-mail（）函数发送带有附件的电子邮件。
它适用于gmail，但雅虎的附件大小为空（0字节）。
这是我使用的附件代码：
$xMessage .= "Content-type:text/html; charset=iso-8859-1'r'n";
$xMessage .= "Content-Transfer-Encoding: 7bit'r'n'r'n";
$xMessage .= $message."'r'n'r'n";
$xMessage .= "--".$mime_boundary."'r'n";
$xMessage .= "Content-Type: application/octet-stream; name='"".basename("uploads/attachment_file/".$file['attachment_name'])."'"'r'n";
$xMessage .= "Content-Transfer-Encoding: base64'r'n";
$xMessage .= "Content-Disposition: attachment; filename='"".basename("uploads/attachment_file/".$file['attachment_name'])."'"'r'n";
$content = file_get_contents("uploads/attachment_file/".$file['attachment_name']);
$xMessage.= chunk_split(base64_encode($content));
$xMessage .= "'r'n'r'n";
我应该怎么做才能在雅虎中获得附件？
将/r/n更改为
$eol = PHP_EOL;
并更改
"Content-Disposition: attachment; filename='"".basename("uploads/attachment_file/".$file['attachment_name'])."'"'r'n";
至
"Content-Disposition: attachment; filename='"".basename("uploads/attachment_file/".$file['attachment_name']).$eol.$eol;
