php与mysql搭建用户管理平台
效果图
前期准备
数据库准备
1、在mysql中创建数据库member
CREATE DATABASE MEMBER;2、根据id、username、psd、email、sex、createtime、ad七个字段建立数据表userinfo
CREATE TABLE userinfo(
id INT(8) PRIMARY KEY,
username VARCHAR(32) NOT NULL,
psd VARCHAR(32) NOT NULL,
email VARCHAR(32) NOT NULL,
sex TINYINT(1) NOT NULL,
createtime DATE NOT NULL,
ad TINYINT(1) NOT NULL
)3、插入几条用户信息
insert into userinfo values(1,'张三','1223456','1233@163.com','1','2002-11-01','0');
insert into userinfo values(2,'李四','1234256','1223@163.com','0','2004-02-01','0');
insert into userinfo values(3,'王五','12123456','1243@163.com','1','2001-03-11','0');
insert into userinfo values(4,'赵六','1252246','1237@163.com','1','2005-04-21','0');
insert into userinfo values(5,'钱七','1236356','1283@163.com','1','2001-05-11','0');
框架引入
bootstrap
平台界面设计布局与组件用到bootstrap框架，采取直接引入的方式
bootstrap地址：警告框（Alert） · Bootstrap v4 中文文档 v4.6 | Bootstrap 中文网 (bootcss.com)
引入方式：下载bootstrap生产文件，并通过直接引入使用。
<script src="jquery.3.7.1/jquery-3.7.1.js"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-icons@1.10.0/font/bootstrap-icons.css">
<script src="https://cdn.bootcss.com/popper.js/1.14.7/umd/popper.min.js"></script>
<link rel="stylesheet" href="bootstrap-4.6.2-dist/css/bootstrap.min.css">
<script src="bootstrap-4.6.2-dist/js/bootstrap.min.js"></script>
layui
layui地址： 开始使用 - Layui 文档
用户管理系统中编辑用户信息需要使用到信息弹窗，这里采用layui的Layer弹出层来实现。
通过进入官网直接下载layui文件，随后直接引入即可使用
<script src="layui/layui.js"></script>用户管理平台
user.php
user.php文件作为用户管理平台，包括侧边栏页面切换和，主部用户信息展示。用户信息展示包括搜索框实现php访问数据库查询，编辑按钮编辑数据库用户数据，删除按钮进行用户信息删除，以及管理员设置，后台添加或删除管理员权限。

删除文件通过在php中连接数据库member的userinfo表，根据主页面传来的id数据进行识别定位，并且调用sql删除语句，“delete from userinfo where id = $id”;进行数据库中用户信息的删除。在user.php中通过del方法调用即可。

?>update.php
用户信息修改功能通过update.php文件配合updatePost.php文件实现，仍然通过首页传递的选中id参数，进入update.php进行数据库连接查询，并显示该用户的信息记录。此时update.php文件将通过layer弹窗进行展示。可是实现不跳转修改，在修改过后，利用表单的Post传递数据到updatePost.php文件。

编辑功能文件updatePost.php利用$_POST[]来接收update.php已经进行修改的数据，并连接数据库调用sql语句"update userinfo set ***='$***'来进行数据修改。同时修改后刷新页面，调用close方法关闭弹窗，使得数据快速更新。实现后台用户数据编辑。

?>总结
php连接mysql主要利用sql增删改查的语句调用，来进行用户与管理员的权限管理和信息删改。配合bootstrap和layui框架，搭建合理的用户管理平台，更好的实现系统集中管理已注册用户。
