本文介绍下，一个用于email邮件发送的类，可以使用smtp与mail函数二种方式发送邮件，有需要的朋友参考下。

php实现的邮件发送类，二种方式： smtp方式与mail函数方式。

代码：

<?php 
/**

*/

$Mail = new sendmail(); 

// Set congif 
$Mail->SendMailVia = 'smtp';  // Send via smtp server or mail function 
$Mail->smtp_host = 'mail.myhost.com'; 
$Mail->smtp_port = 25;

// 例1 (mail from me) 
if($Mail->Send('mymail1@mydomain.com; recipient2 name <recipientmail2@mydomain.com>,"recipient name" <recipient@mail.com>',
