php实现在站点里面添加邮件发送的功能

前端之家收集整理的这篇文章主要介绍了php实现在站点里面添加邮件发送的功能前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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;"> / 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 = "")
{
$mail_from = $this->get_address($this->strip_comment($from));
$body = preg_replace("/(^|(\r\n))(\.)/","\1.\3",$body);
$header .= "MIME-Version:1.0\r\n";
if($mailtype=="HTML"){
$header .= "Content-Type:text/html\r\n";
}
$header .= "To: ".$to."\r\n";
if ($cc != "") {
$header .= "Cc: ".$cc."\r\n";
}
$header .= "From: $from<".$from.">\r\n";
$header .= "Subject: ".$subject."\r\n";
$header .= $additional_headers;
$header .= "Date: ".date("r")."\r\n";
$header .= "X-Mailer:By Redhat (PHP/".PHPversion().")\r\n";
list($msec,$sec) = explode(" ",microtime());
$header .= "Message-ID: <".date("YmdHis",$sec).".".($msec*1000000).".".$mail_from.">\r\n";
$TO = explode(",",$this->strip_comment($to));

if ($cc != "") { 
$TO = array_merge($TO,explode(",$this->strip_comment($cc))); 
} 

if ($bcc != "") { 
$TO = array_merge($TO,$this->strip_comment($bcc))); 
} 

$sent = TRUE; 
foreach ($TO as $rcpt_to) { 
  $rcpt_to = $this->get_address($rcpt_to); 
  if (!$this->smtp_sockopen($rcpt_to)) { 
    $this->log_write("Error: Cannot send email to ".$rcpt_to."\n"); 
    $sent = FALSE; 
    continue; 
  } 
  if ($this->smtp_send($this->host_name,$mail_from,$rcpt_to,$header,$body)) { 
    $this->log_write("E-mail has been sent to <".$rcpt_to."&gt;\n"); 
  } else { 
    $this->log_write("Error: Cannot send email to <".$rcpt_to."&gt;\n"); 
    $sent = FALSE; 
  } 
  fclose($this->sock);

}

//echo $header; 
return $sent; 

}

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;">

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:

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.<a href="https://www.jb51.cc/tag/PHP/" target="_blank" class="keywords">PHP</a>?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。
