PHP implementation in the site to add a message to send the function _php instance

The following summer blog about how to add a message in the site to send the function.
First, you need to download an SMTP PHP mail send 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 = +, $auth = False, $user, $pass) {$this->debug = FA     LSE;     $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 = "", $additi     Onal_headers = "") {$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.

This type of e-mail send a lot of online, you can pick a favorite on the line, the above code to save as ZC_Email.class.php file, and then in use when the direct include_once ("ZC_Email.class.php") on it, the code is as follows :

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

This is the message sent to the class has been embedded in the page, the next step in the page to send the content, I am here the system is the user after the successful purchase of the send, the example code is as follows:

//Space purchase successfully sent mail $smtpserver = "smtp.163.com";//SMTP server $smtpserverport =25;//SMTP Server Port $smtpusermail = "xiariboke@163.com";//smtp Server user Mailbox $smtpemailto = "xiariboke@qq.com";//Send to who $smtpuser =     "xiariboke@163.com"; user account of//SMTP server $smtppass = "Xiariboke"; user password for//smtp server $mailsubject = "Boutique Door net Hong Kong space purchase";//Mail subject $mailbody = "Successful purchase of Hong Kong space $size m space, the purchase of the domain name: $domain purchase Time:". Format_date (2). "Expiry: $lasttime". Format_date (Time (), 5) ;//mail content $mailtype = "txt";//Message Format (html/txt), TXT as text mail ########################################## $smtp = new SMT     P ($smtpserver, $smtpserverport, True, $smtpuser, $smtppass);//A true in this case means that authentication is used, otherwise, no authentication is used. $SMTP->debug = false;//whether to display debug information sent $smtp->sendmail ($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailt     YPE); Mail Send end showmsg (' Buy success! ', ' zc_link_list.php?sort=2 '); 

Where the SMTP server user mailbox and password itself to set up, this is sent to a designated mailbox, of course, can be customized to their own, the variables are in my site use, if you do not need to be able to modify a little bit, here not much to say.
I hope this article will help you learn PHP programming.
