}

/*用法 - 例如:mimetype 为 "image/gif"
$mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$mimetype);
$mailfile->sendfile();

$subject -- 主题
$sendto -- 收信人地址
$replyto -- 回复地址
$message -- 信件内容
$filename -- 附件文件名
$downfilename -- 下載的文件名
$mimetype -- mime类型
*/
?>

Demo

require_once('emailclass.php');

//发送邮件

//主題
$subject = "test send email";

//收件人
$sendto = 'abc@163.com';

//發件人
$replyto = 'cdf@163.com';

//內容
$message = "test send email content";

//附件
$filename = 'test.jpg';

//附件類別
$mimetype = "image/jpeg";

$mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$excelname,$mimetype);
$mailfile->sendfile();
