 站长推荐:一个PHP邮件发送类及示例程序(已实测验证) |
一个PHP邮件发送的类,支持用已有的电子信箱账号发信,也支持自己搭建的SMTP服务器。强烈建议使用自己搭建的SMTP服务器。本程序由站长使用163信箱账号测试无误,又用Mail Direct Pro 2.4搭建了SMTP服务器,测试无误。由于免费信箱的一些发送时间、次数限制和很多大网站存在的反垃圾邮件问题,强烈建议使用自己搭建的SMTP服务器。Mail Direct Pro 不足1M,对于个人使用极为方便,并且经过实测证明与本源码搭配运行效果十分理想,因此强烈建议使用。
SMTP类文件: MyPHPMailer.php

测试文件 sendtest.php
代码如下:
<?php
/*
MyPHPMailer类使用方法示例程序
*/
require("MyPHPMailer.php");
//<方法一>使用已有的电子信箱账号发信:
/*-------------------------------------------------
$smtpserver = "smtp.xx.com"; //SMTP服务器
$smtpserverport =25; //SMTP服务器端口
$smtpusermail = "rznqp@163.com"; //发信用的合法邮箱
$smtpuser = "rznqp@163.com"; //邮箱用户帐号
$smtppass = "123456"; //邮箱用户密码
------------------------------------------------*/
//<方法二>使用匿名的SMTP服务器(自己搭建的SMTP)-------
$smtpserver = "localhost"; //SMTP服务器
$smtpserverport =25; //SMTP服务器端口
$smtpusermail = "admin@17php.com"; //显示的发信人信箱
//------------------------------------------------
$smtpemailto = "rznqp@163.com"; //发送给谁,批量发送用“,”隔开
$mailsubject = "向您请教"; //邮件主题
$mailtype = "HTML"; //邮件格式(HTML或TXT),TXT为文本邮件
$mailbody = "请问PHP安装注意哪些事情?谢谢。"; //邮件正文
// 当使用已有电子信箱账号发信时:
// $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);
// 当使用匿名SMTP发送时:
$smtp = new smtp($smtpserver,$smtpserverport);
$smtp->debug = TRUE; //是否打印出发送过程中的调试信息
//执行发送
$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
?>
唯一需要说明的是,$smtpusermail为发信人信箱。如果使用已有的账号,一定要正确填写信箱,如果使用自己的SMTP,则可以随便设置,只要SMTP允许即可。 |
