第一步：php连接数据库：dbconnection.php

<?php

$server = "(local)";
$_uid = "adweb";
$_pwd = "loveyou";
$_database = "addev";

 function sqlsrv_connect( $server , $uid ,$pwd,$db  ){
    
    $connect_id= mssql_connect($server, $uid, $pwd);
           //echo $connect_id ;
   if($connect_id){
               if (mssql_select_db($db,$connect_id))
                   return $connect_id ;
    else
     echo mssql_get_last_message() ; 
           }
   else
    echo mssql_get_last_message() ;
 }

 function sqlsrv_query($SQL,$conn  ) {
   returnmssql_query( $SQL ,$conn ) ;
 }

function sqlsrv_num_rows($n) {
 
 return mssql_num_rows($n) ;

}
function sqlsrv_fetch_array($n) {

  returnmssql_fetch_array($n);
}
//调用函数，连接数据库
$conn = sqlsrv_connect( $server , $_uid ,$_pwd,$_database  ) ;

?>

第二步：邮箱类email.class.php

<?
class smtp
{

var $smtp_port;
var $time_out;
var $host_name;
var $log_file;
var $relay_host;
var $debug;
var $auth;
var $user;
var $pass;

var $sock;

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 HELOcommand
$this->log_file ="";

$this->sock = FALSE;
}

function sendmail($to, $from, $subject = "", $body = "", $mailtype,$cc = "", $bcc = "", $additional_headers = "")
{
$mail_from =$this->get_address($this->strip_comment($from));
$body = ereg_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 .=
