基于php+mysql的简单图书管理系统（附源码）

一、模块设计

二、技术选型

IDE：phpstorm

mysql：5.1

php：7.3.29

运行工具：phpstudy

三、数据库设计

用户表：

CREATE TABLE `t_user` (`id` int(11) NOT NULL AUTO_INCREMENT,`uname` varchar(255) DEFAULT NULL,`upass` varchar(255) DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8

图书表：

CREATE TABLE `t_book` (`id` bigint(20) NOT NULL AUTO_INCREMENT,`bookname` varchar(512) NOT NULL,`author` varchar(512) NOT NULL,`publish` varchar(512) NOT NULL,`isbn` varchar(512) NOT NULL,`introduction` varchar(512) NOT NULL,`language` varchar(128) NOT NULL,`price` int(11) DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8

四、核心代码

DBConnection.php

<?phpclass DbConnection
{public static function getConnection(): mysqli{$connection = mysqli_connect('127.0.0.1','root','root','bookmanagesys','3306'); //创建数据库连接if(!$connection){ //如果失败die('连接mysql数据库失败'.mysqli_error()); //显示出错误信息}mysqli_select_db( $connection, "bookmanagesys");mysqli_set_charset($connection, "utf8");return $connection;}}

BookController.php

<?php
include '../bean/User.php';
include '../dao/BookDao.php';header("Content-Type: application/json;charset=UTF-8");// 从请求中获取原始数据
$json = file_get_contents('php://input');// 将其转换为 PHP 对象
$param = json_decode($json);$method = $param->method;$bookDao = new BookDao();
$res = new Res();switch ($method){case 'queryAll'://查询全部$res->setData($bookDao->queryAll($param));$res->setSuccess(true);break;case 'save'://保存$res->setData($bookDao->save($param));$res->setSuccess(true);break;case 'update'://更新$res->setData($bookDao->update($param));$res->setSuccess(true);break;case 'delete'://删除$res->setData($bookDao->delete($param));$res->setSuccess(true);break;
}echo json_encode($res);?>
