如题
贴一下代码
<?php require_once('../Connections/connect.php'); ?>
<?php
// *** Validate request to login to this site.
session_start();
?>
<?php
   //验证用户输入是否和验证码一致

        { 
                if(strcmp($_SESSION['authnum'],md5($HTTP_POST_VARS['authinput']))==0) 
                       { 
//以上为验证添加-----------------------//session_unregister('authnum');
