Demo

<?phprequire_once('emailclass.php');//發送郵件//主題$subject = "test send email";//收件者$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();?>
