HomeBackend DevelopmentPHP TutorialHow to add an email sending function to the site in PHP

前面我们和大家讲解了一下如何用phpmaill发送邮件,相信大家都对phpmaill发送邮件有所掌握,那今天继续讲解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 =""; 
     
    $this->sock = FALSE; 
  } 
 
  /* Main Function */
  function sendmail($to, $from, $subject = "", $body = "", $mailtype, $cc = "", $bcc = "", $additional_headers = "") 
  {

    } 
     
    if ($bcc != "") {

  switch($extension){ 
    case ".gif": 
      $filedata[&#39;type&#39;] = "image/gif"; 
      break; 
    case ".gz": 
      $filedata[&#39;type&#39;] = "application/x-gzip"; 
      break; 
    case ".htm": 
      $filedata[&#39;type&#39;] = "text/html"; 
      break; 
    case ".html": 
      $filedata[&#39;type&#39;] = "text/html"; 
      break; 
    case ".jpg": 
      $filedata[&#39;type&#39;] = "image/jpeg"; 
      break; 
    case ".tar": 
      $filedata[&#39;type&#39;] = "application/x-tar"; 
      break; 
    case ".txt": 
      $filedata[&#39;type&#39;] = "text/plain"; 
      break; 
    case ".zip": 
      $filedata[&#39;type&#39;] = "application/zip"; 
      break; 
    default: 
      $filedata[&#39;type&#39;] = "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(&#39;购买成功!&#39;,&#39;ZC_Link_List.php?sort=2&#39;);

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。

php怎么把负数转为正整数php怎么把负数转为正整数Apr 19, 2022 pm 08:59 PM

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

php怎么实现几秒后执行一个函数php怎么实现几秒后执行一个函数Apr 24, 2022 pm 01:12 PM

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php怎么除以100保留两位小数php怎么除以100保留两位小数Apr 22, 2022 pm 06:23 PM

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

php怎么根据年月日判断是一年的第几天php怎么根据年月日判断是一年的第几天Apr 22, 2022 pm 05:02 PM

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php怎么判断有没有小数点php怎么判断有没有小数点Apr 20, 2022 pm 08:12 PM

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

php怎么替换nbsp空格符php怎么替换nbsp空格符Apr 24, 2022 pm 02:55 PM

php字符串有没有下标php字符串有没有下标Apr 24, 2022 am 11:49 AM

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。
