var $mailHTML = ""; // HTML format letter body
var $mailAttachments = ""; // Attachment

使用方法： 
 
Include “email.class” 

$mail->setTo("a@a.com"); //收件人 
$mail-> setCC（"b@b.com,c@c.com"）; //抄送 
$mail-> setCC（"d@b.com,e@c.com"）; //秘密抄送 
$mail->setFrom(“f@f.com”);//发件人 
$mail->setSubject(“主题”) ; //主题 
$mail->setText(“文本格式”) ;//发送文本格式也可以是变量 
$mail->setHTML(“html格式”) ;//发送html格式也可以是变量 
$mail->setAttachments(“c:a.jpg”) ;//添加附件,需表明路径 
$mail->send(); //发送邮件
