php邮件发送,php发送邮件的类

　　smtp.class.php 这个是类把他做保存到一个文件中.
复制代码 代码如下:

测试代码：
复制代码 代码如下:
<?
//ok的邮箱发送。
include smtp.class.php;
$port =25; //smtp服务器的端口，一般是 25
$smtpuser = 你的邮箱@163.com; //您登录smtp服务器的用户名
$smtppwd = 你邮箱的密码; //您登录smtp服务器的密码
$mailtype = TXT; //邮件的类型，可选值是 TXT 或 HTML ,TXT 表示是纯文本的邮件,HTML 表示是 html格式的邮件
$sender = 你的邮箱@163.com;
//发件人,一般要与您登录smtp服务器的用户名($smtpuser)相同,否则可能会因为smtp服务器的设置导致发送失败
$smtp = new smtp($smtpserver,$port,true,$smtpuser,$smtppwd,$sender);
$smtp->debug = true; //是否开启调试,只在测试程序时使用，正式使用时请将此行注释
$to = 你要发给的那个人的邮箱地址; //收件人
$subject = 你好;
