我自己借用精华区里的mime类写了一个基本的发信小东东(2)

　　 sendmail.php4

<?
//加载发送附件的类
require('html_mime_mail.inc');

if($update!=""){  //如果带附件

    //上传附件
    if(!file_exists("c:/ftptmp/".$myfile_name)){
        if(copy($myfile,"c:/ftptmp/".$myfile_name)){
            //读取附件
            $attachment = fread($fp = fopen("c:/ftptmp/".$myfile_name, 'r'), filesize($myfile));
            fclose($fp);
            //unlink("c:/ftptmp/".$myfile_name);删掉
        }
        else {
            echo "上传文件失败！";
            exit();
        }
    }
    else{
        echo "文件重名！";
        exit();
    }


    //新建一个类的实例，并加入附件
    $mail = new html_mime_mail();
