    $mail->Password = 'xxx';             // SMTP 密码  部分邮箱是授权码(例如163邮箱) 
    $mail->SMTPSecure = 'ssl';                    // 允许 TLS 或者ssl协议 
    $mail->Port = 465;                            // 服务器端口 25 或者465 具体要看邮箱服务器支持 

    $mail->setFrom('[email protected]', 'PHPMailer');  //发件人 
    $mail->addAddress('[email protected]', 'TANKING');  // 收件人 
    //$mail->addAddress('[email protected]');  // 可添加多个收件人 
    $mail->addReplyTo('[email protected]', 'PHPMailer'); //回复的时候回复给哪个邮箱 建议和发件人一致

    //发送附件 
    // $mail->addAttachment('../xy.zip');         // 添加附件
