怎么把php导出的Excel 作为邮件发送

<br />header("Content-type:application/octet-stream");<br />    header("Accept-Ranges:bytes");<br />    header("Content-type:application/vnd.ms-excel");  <br />    header("Content-Disposition:attachment;filename=".$filename.".xls");<br />    header("Pragma: no-cache");<br />    header("Expires: 0");<br /><br />    if (!empty($title)){<br />        foreach ($title as $k => $v) {<br />            $title[$k]=iconv("UTF-8", "GB2312",$v);<br />        }<br />        $title= implode("\t", $title);<br />        echo "$title\n";<br />    }<br />    if (!empty($data)){<br />        foreach($data as $key=>$val){<br />            foreach ($val as $ck => $cv) {<br />                $data[$key][$ck]=iconv("UTF-8", "GB2312", $cv);<br />            }<br />            $data[$key]=implode("\t", $data[$key]);<br />        }<br />        echo implode("\n",$data);<br />    }<br />

<br />$mail    = new PHPMailer();   <br />    $mail->CharSet    = 'UTF-8';           <br />    $mail->IsSMTP();               <br />    $mail->SMTPAuth   = true;                 <br />    $mail->SMTPSecure = '';                   <br />    $mail->Host       = $config['SMTP_HOST'];  // SMTP 服务器  <br />    $mail->Port       = $config['SMTP_PORT'];  // SMTP服务器的端口号  <br />    $mail->Username   = $config['SMTP_USER'];  // SMTP服务器用户名  <br />    $mail->Password   = $config['SMTP_PASS'];  // SMTP服务器密码  <br />    $mail->SetFrom($config['FROM_EMAIL'], $config['FROM_NAME']);  <br />    $replyEmail       = $config['REPLY_EMAIL']?$config['REPLY_EMAIL']:$config['FROM_EMAIL'];  <br />    $replyName        = $config['REPLY_NAME']?$config['REPLY_NAME']:$config['FROM_NAME'];  <br />    $mail->AddReplyTo($replyEmail, $replyName);  <br />    $mail->Subject    = $subject;  <br />    $mail->MsgHTML($body);  <br />    $mail->AddAddress($to, $name);  <br />    if(is_file($attachment)){                   // 添加附件  <br />        $mail->AddAttachment($attachment);  <br />    }  <br />    return $mail->Send()<br />
