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:

  1. <?php
  2. class smtp 
  3. { 
  4.   /* Public Variables */
  5.   public $smtp_port; 
  6.   public $time_out; 
  7.   public $host_name; 
  8.   public $log_file; 
  9.   public $relay_host; 
  10.   public $debug; 
  11.   public $auth; 
  12.   public $user; 
  13.   public $pass; 
  14.    
  15.   /* Private Variables */
  16.   private $sock; 
  17.  
  18.   /* Constractor */
  19.   function smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass) 
  20.   { 
  21.     $this->debug = FALSE; 
  22.     $this->smtp_port = $smtp_port; 
  23.     $this->relay_host = $relay_host; 
  24.     $this->time_out = 30; //is used in fsockopen() 
  25.     # 
  26.     $this->auth = $auth;//auth 
  27.     $this->user = $user; 
  28.     $this->pass = $pass; 
  29.     # 
  30.     $this->host_name = "localhost"; //is used in HELO command 
  31.     $this->log_file =""; 
  32.      
  33.     $this->sock = FALSE; 
  34.   } 
  35.

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

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. //空间购买成功发送邮件
  2.     $smtpserver = "smtp.163.com";//SMTP服务器 
  3.     $smtpserverport =25;//SMTP服务器端口 
  4.     $smtpusermail = "xiariboke@163.com";//SMTP服务器的用户邮箱 
  5.     $smtpemailto = "xiariboke@qq.com";//发送给谁 
  6.     $smtpuser = "xiariboke@163.com";//SMTP服务器的用户帐号 
  7.     $smtppass = "xiariboke";//SMTP服务器的用户密码 
  8.     $mailsubject = "精品门业网香港空间购买";//邮件主题 
  9.     $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 
  10.     $mailtype = "TXT";//邮件格式（HTML/TXT）,TXT为文本邮件 
  11.     ########################################## 
  12.     $smtp = new smtp($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. 
  13.     $smtp->debug = false;//是否显示发送的调试信息 
  14.     $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype); 
  15.     //邮件发送结束
  16.  
  17.     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。
