本项目搭建了一个简单的页面，用php+mysql来实现登录、注册以及注销的功能。
效果展示
从右上方可以看到，当前是未登录的主页
点击登录，来到登录页面
如果还没注册，就点击进行注册
登录成功进入主页，看到右上方显示当前登录的用户名。点击用户名后的退出，即可退出登录。
实现过程
1.项目目录
2.主要实现代码
config.php保存数据库连接信息
<?php //数据库连接信息 $host='localhost'; //数据库服务器主机名 $user='root'; //数据库用户名 $password='root'; //数据库用户密码 $dbname='itcast'; //数据库名 //开启session session_start();
register.php注册功能
<?php require'./config.php'; //引入公共文件开启session功能 // require'./html/register.html'; //调用内容模板 if($_POST){ $link=mysqli_connect($host,$user,$password,$dbname); if(!$link){ display('数据库连接失败。'.mysqli_connect_error()); } mysqli_set_charset($link,'utf8'); $fields= array('name', 'password', 'sex', 'email', 'course', 'channel', 'message') ; //$fields= ['name', 'password', 'sex', 'email', 'course', 'channel', 'message'] ; //$data[]; $data=array(); foreach($fields as $v){ $data[$v]=isset($_POST[$v])?$_POST[$v]:''; } if(is_array($data['channel'])){ $data['channel']==implode('，', $data['channel']); } foreach($data as $k=>$v){ $data[$k]=mysqli_real_escape_string($link,$v); } $result=mysqli_query($link,"SELECT 1 FROM `user` WHERE `name` ='{$data['name']}'"); if(!$result){ display('数据库操作失败：'.mysqli_error($link)); } if(mysqli_num_rows($result)){ display('该用户名已被注册！'); } $sql_values=implode("','",$data); $sql_fields=implode("`,`",$fields); //执行SQL语句 $result=mysqli_query($link,"INSERT INTO user (`$sql_fields`) VALUES ('$sql_values')"); if($result){ header('Location:login.php'); exit; }else{ display('数据库操作失败：'.mysqli_error($link)); } } display(); function display($message=false){ require'./html/register.html'; exit; }
login.php登录功能
<?php require'./config.php'; //引入公共文件开启session功能 if($_POST){ $link=mysqli_connect($host,$user,$password,$dbname); if(!$link){ display('数据库连接失败。'.mysqli_connect_error()); } mysqli_set_charset($link,'utf8'); //接收用户名和密码 $name=isset($_POST['name'])? $_POST['name']:''; $password=isset($_POST['password'])? $_POST['password']:''; $name=mysqli_real_escape_string($link,$name); $password=mysqli_real_escape_string($link,$password); $result=mysqli_query($link,"SELECT 1 FROM `user` WHERE `name` ='$name' AND `password`='$password'"); if(!$result){ display('数据库操作失败：'.mysqli_error($link)); } if(mysqli_num_rows($result)){ $_SESSION['user']=$name; header('Location:index.php'); exit; }else{ display('登录失败，用户名或密码有误。'); } } display(); function display($message=false){ require'./html/login.html'; exit; }
index.php主页
<?php require'./config.php'; //引入公共文件开启session功能 require'./html/index.html'; //调用内容模板
logout.php注销功能
<?php require'./config.php'; unset($_SESSION['user']); //用户退出功能 header('Location:index.php'); //跳转页面

3.配置mysql数据库
登录phpMyAdmin
新建itcast数据库和user表
4.部署项目
完成以后几步后，把项目部署到phpstudy上，即可打开网站浏览效果。phpstudy的使用可见我另一篇[fastadmin的安装过程]。
