這是一款利用php 與mysql數(shù)據(jù)庫(kù)實(shí)現(xiàn)的用戶注冊(cè)與登錄代碼,功能也是比較簡(jiǎn)單實(shí)用的用戶注冊(cè)程序,同時(shí)也加了用戶登錄時(shí)驗(yàn)證碼程序,這樣做就安全了很多,代碼如下:

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">

<html xmlns="http://www.111cn.net/1999/xhtml">

<head>

<meta http-equiv="content-type" content="text/html; charset=gb2312" />

<title>在后臺(tái)增加用戶</title>

</head>

<body>

<?php

require_once("config.php");

   if(isset($_post["submit2"])){

   mysql_select_db('a0807000225'); //這個(gè)是數(shù)據(jù)庫(kù)表

   $author=$_session["user_name"];

   define(all_ps,"jinquan");

   echo $username=$_post["username"];

   echo $password=md5($password=$_post["password"].all_ps);

   echo "</br>";

   if($username){

   if($password){

      $str = "insert into `dx_user_list` ( `uid` , `m_id` , `username` , `password` ) values (ascii( null ) , '1', '$username', '$password');";

   $rs=mysql_query($str,$conn);

   mysql_close($conn);

  }//開(kāi)源代碼Vevb.com

  if($rs){

    echo"<script>alert('新增成功');location.href='yonghuzc.php'</script>";

    }else{

    echo"<script>alert('新增失敗');location.href=''yonghuzc.php'</script>";

    }

  }

}
