下面夏日博客来讲下如何在站点里面添加一个邮件发送的功能。
首先需要下载一个smtp 的 php 邮件发送类,代码如下:

这类的邮件发送类网上有许多,可以挑一款自己喜欢的就行,将以上的代码保存为 ZC_Email.class.php 文件,然后在使用的时候直接 include_once("ZC_Email.class.php") 就可以了,代码如下:

?
1
2
3
<?php
include_once("ZC_Email.class.php");
?>

这是将邮件的发送类已经嵌入到页面中了,下一步就要在页面进行内容的发送了,我这里的系统是用户购买成功后进行发送,实例代码如下:

?
1
2
3
4

6

//空间购买成功发送邮件
  $smtpserver = "smtp.163.com";//SMTP服务器
  $smtpserverport =25;//SMTP服务器端口
  $smtpusermail = "xiariboke@163.com";//SMTP服务器的用户邮箱
  $smtpemailto = "xiariboke@qq.com";//发送给谁
  $smtpuser = "xiariboke@163.com";//SMTP服务器的用户帐号
  $smtppass = "xiariboke";//SMTP服务器的用户密码
  $mailsubject = "精品门业网香港空间购买";//邮件主题
  $mailbody = "成功购买香港空间 $size M空间,购买域名为:$domain 购买时间为:".format_date(time(),2)." 到期时间为: $lasttime ".format_date(time(),5);//邮件内容
  $mailtype = "TXT";//邮件格式(HTML/TXT),TXT为文本邮件
  ##########################################
  $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证.
  $smtp->debug = false;//是否显示发送的调试信息
  $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
  //邮件发送结束
 
  showmsg('购买成功!','ZC_Link_List.php?sort=2');

其中 SMTP 服务器的用户邮箱和密码自己要设置好,这是发给指定的一个邮箱,当然可以自定义改成自己的,这里面的变量都是我站点内使用的,如果不需要可以自己稍微修改一下,这里不多讲了。
希望本文所述对大家学习php程序设计有所帮助。
