php实现在站点里面添加邮件发送的功能_php实例

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
class smtp
{
  /* Public Variables */
  public $smtp_port;
  public $time_out;
  public $host_name;
  public $log_file;
  public $relay_host;
  public $debug;
  public $auth;
  public $user;
  public $pass; 

  /* Private Variables */
  private $sock; 

  /* Constractor */
  function smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass)
  {
    $this->debug = FALSE;
    $this->smtp_port = $smtp_port;
    $this->relay_host = $relay_host;
    $this->time_out = 30; //is used in fsockopen()
    #
    $this->auth = $auth;//auth
    $this->user = $user;
    $this->pass = $pass;
    #
    $this->host_name = "localhost"; //is used in HELO command
    $this->log_file ="";

  }

  $filedata['context'] = $image_data;
  $filedata['filename']= basename($image_tag);
  $extension=substr($image_tag,strrpos($image_tag,"."),strlen($image_tag)-strrpos($image_tag,"."));
  switch($extension){
    case ".gif":
      $filedata['type'] = "image/gif";
      break;
    case ".gz":
      $filedata['type'] = "application/x-gzip";
      break;
    case ".htm":
      $filedata['type'] = "text/html";
      break;
    case ".html":
      $filedata['type'] = "text/html";
      break;
    case ".jpg":
      $filedata['type'] = "image/jpeg";
      break;
    case ".tar":
      $filedata['type'] = "application/x-tar";
      break;
    case ".txt":
      $filedata['type'] = "text/plain";
      break;
    case ".zip":
      $filedata['type'] = "application/zip";
      break;
    default:
      $filedata['type'] = "application/octet-stream";
      break;
  }
  return $filedata;
  } 

} // end class
?>

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 $size M空间，购买域名为：$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。
