php mysql用户注册登陆代码
这是一款利用php 与mysql数据库实现的用户注册与登录代码,功能也是比较简单实用的用户注册程序,同时也加了用户登录时验证码程序,这样做就安全了很多,代码如下:
<!doctype html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=gb2312" />
<title>在后台增加用户</title>
</head>
<body>
<?php
require_once ("config.php");
if (isset($_post["submit2"])) {
mysql_select_db('a0807000225'); //这个是数据库表
$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);
}
if ($rs) {
echo "<script>alert('新增成功');location.href='yonghuzc.php'</script>";
} else {
echo "<script>alert('新增失败');location.href=''yonghuzc.php'</script>";
}
}
