Php adds the email sending function to the site _ php instance

A simple space management system is developed to store all domain name spaces in the database for management. When the user renews the domain name space, an email is sent for notification, then, I will perform the "batch" operation here. It is easy to use the mail sending function. How can I implement the mail sending function? Next, I will talk about how to add a mail sending function to the website in my summer blog.
First, download an smtp php mail sending class. The Code is as follows:

<?phpclass 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 = "")   {     $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, explode(",", $this->strip_comment($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.">\n");       } else {         $this->log_write("Error: Cannot send email to <".$rcpt_to.">\n");         $sent = FALSE;       }       fclose($this->sock);       $this->log_write("Disconnected from remote host\n");     }     echo "

There are a lot of such email sending types on the Internet. You can just pick one that you like and save the above Code as the ZC_Email.class.php file, and then directly export de_once ("ZC_Email.class.php") when using it ") the Code is as follows:

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

This is to embed the mail sending class into the page, and the next step is to send the content on the page. My system here is to send the content after the user purchases it successfully. The instance code is as follows:

// Send the email $ smtpserver = "smtp.163.com"; // SMTP server $ smtpserverport = 25; // SMTP server port $ smtpusermail = "xiariboke@163.com "; // SMTP server user email $ smtpemailto = "xiariboke@qq.com"; // send to $ smtpuser = "xiariboke@163.com"; // SMTP server user account $ smtppass = "xiariboke "; // SMTP server user password $ mailsubject = ""; // Email Subject $ mailbody = "$, the domain name is: $ domain :". format_date (time (), 2 ). "expiration time: $ lasttime ". format _ Date (time (), 5); // mail content $ mailtype = "TXT"; // mail format (HTML/TXT ), TXT is a text email #################################### ###### $ smtp = new smtp ($ smtpserver, $ smtpserverport, true, $ smtpuser, $ smtppass); // here, true indicates that authentication is used; otherwise, authentication is not used. $ smtp-> debug = false; // whether to display the sent debugging information $ smtp-> sendmail ($ smtpemailto, $ smtpusermail, $ mailsubject, $ mailbody, $ mailtype ); // The email sending ends with showmsg ('purchase successful! ', 'Zc _ Link_List.php? Sort = 2 ');

The SMTP server user's email address and password should be set by yourself. This is a designated email address. Of course, you can change it to your own. The variables here are all used in my site, if you do not need it, you can modify it by yourself.
I hope this article will help you learn php programming.
