php实现在站点里面添加邮件发送的功能
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:
<?php

public$host_name;
public$log_file;

private$sock;
/*Constractor*/

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:
<?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:
//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
$mailbody="成功购买香港空间$sizeM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
##########################################
$smtp=newsmtp($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。
