} 
/*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

<?php
	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();
