PHP implementation in the site to add mail to send the function _php instance

Below the summer blog to talk about how to add a message to the site to send the function.
First you need to download a PHP mail send class for SMTP, the code is as follows:

<?php class SMTP {/* Public Variables/public $smtp _port;

This type of mail sent online there are many, you can pick a favorite on the line, the above code to save the ZC_Email.class.php file, and then use 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 is to send the content on the page, my system here is the user to purchase a successful send, the example code is as follows:

//space purchase successfully sent mail $smtpserver =" smtp.163.com ";//smtp Server $smtpserverport =25;//SMTP Service  Port $smtpusermail = "xiariboke@163.com";//smtp server's user mailbox $smtpemailto = "xiariboke@qq.com"; Who to send to $smtpuser = 
    "xiariboke@163.com"//SMTP Server user account $smtppass = "Xiariboke";//smtp user password for the server $mailsubject = "Boutique Door Industry Network Hong Kong Space purchase";/Mail subject $mailbody = "Successful purchase of Hong Kong space $size m space, purchase domain name: $domain purchase time is:". Format_date (Times (), 2). "Expires in: $lasttime". Format_date (Time (), 5) ;//message content $mailtype = "txt";//Message Format (html/txt), TXT for text mail ########################################## $smtp = new 
    SMTP ($smtpserver, $smtpserverport, True, $smtpuser, $smtppass);//One of the true in this is to use authentication, otherwise authentication is not used. $SMTP->debug = false;//whether to display the debug information sent $smtp->sendmail ($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailt 
    YPE); Mail sent over ShowMsg (' buy success!
', ' zc_link_list.php?sort=2 '); 

The SMTP server in which the user's mailbox and password to set up, this is sent to a designated mailbox, of course, can be customized to their own, which variables are used in my site, if you do not need to be able to modify their own slightly, here is not much to say.
Hopefully this article will help you learn about PHP programming.
