？ Experiment 7 implementation of PHP management system based on MySQL

Purpose and requirement of the experiment ：

1. Enable students to master Mysql Configuration of database 、 Create and maintain ;

2. Enable students to master Mysql Data table creation 、 to update 、 Delete and query ;

3. Enable students to master Mysql Database Select sentence ;

4. Enable students to master the use PHP operation Mysql Database method . Experimental content ：

Design and use PHP Complete a simple library information management system . The database is required to use Mysql establish , The design of the data table in the database must meet the requirements in the requirements analysis document , And issue the necessary system E-R chart . utilize PHP The function of completes the connection of the database 、 Data record entry 、 lookup 、 Update and delete Division operation . The input of all data involved in this system adopts HTML Enter the form , Also on Necessary data fields to judge .

（ The final individual score will be judged according to the specific design of your system ）

(1) stay Mysql In the customer console , Use the command library information management system database and table ;（2

Class hours ）

(2) Use PHPMyadmin Tools build the same database and tables .（1 Class hours ）

(3) To write PHP The program completes the functional requirements of the experimental topic .（3 Class hours ） The experiment is pre recorded ：

1、 Analyze the needs of the experiment , And plan the experimental steps , Draw the user's operation flow chart ;

2、 Analyze entities , Draw the experimental E-R chart , And draw the data flow chart of the test ;

3、 According to the experimental needs analysis and E-R Figure designs the database structure , And design the connection between tables ;

4、 Design the database , Create a new database , The name of the database is borrow;

5、 Because you need to register and save user information , So you need to create a new table to save readers' information to this The table is named user_msg, Create five new fields in this table , hold user_id Set the primary key , It is stored inside Basic information of the customer ;

build register, As the user's registration interface ;

10、 newly build check_role.php file , Accept the data submitted by the login form , And analyze whether the user is reading Or system administrator ;

11、 newly build admin.php and reader.php Two documents , As the operation interface of readers and administrators respectively , Enter when the role is administrator admin.php, Enter when the role is an ordinary user reader.php;

12、 When entering admin.php Interface time , Administrators can input information into books . Information can be Make changes , Information can be deleted , You can query the borrowing information of users

File saves book information ;

14、 establish mod_book.php Document and del_book.php file , Implement the modification and deletion of book information ;

15、 User access reader.php In file , You can query the book information , And can perform borrowing operations ;

16、 newly build boorrow_book.php You can borrow books , When you click borrow , Put the book Borrowing status of , Change it to “1”;

17、 Test the system , Check for bug.
