How to write a simple online lending management system through PHP

How to write a simple online lending management system through PHP, specific code examples are required

Introduction:
With the advent of the digital age, library management methods There have also been huge changes. Traditional manual recording systems are gradually being replaced by online borrowing management systems. Online borrowing management systems greatly improve efficiency by automating the process of borrowing and returning books. This article will introduce how to use PHP to write a simple online lending management system and provide specific code examples.

1. System Requirements Analysis
Before starting to write the online lending management system, we need to clarify the basic requirements of the system. A simple online borrowing management system should include the following functions:

Student registration and login: Students can create an account through registration and log in to the system using the account.
Book management: including functions such as adding, editing, and deleting books.
Borrowing management: Students can check the information of borrowable books and implement borrowing and returning operations.
Borrowing record query: Students can query their borrowing records.

2. System Design
After clarifying the system requirements, we need to design the system. During the design process, we need to consider the design of the database and the design of the table structure.

Database design:
- Student table: used to store student information, including student ID, student name, login account and password fields.
- Book table: used to store book information, including book ID, book name, author, publisher and other fields.
- Borrowing record table: used to store student borrowing records, including student ID, book ID, borrowing date, return date and other fields.
Table structure design: Based on demand analysis and database design, we can design the following table structure:
Student table (student):
- student_id: student ID, primary key
- student_name: student name
- student_username: student login account
- student_password: student login password

Book table (book):
- book_id: book ID, primary key
- book_name: book name
- author : Author
- publisher : Publisher
Borrowing record table (borrow_record):
- student_id : Student ID
- book_id: book ID
- borrow_date: borrowing date
- return_date: return date

3. System development
Before system development, we need to set up a server environment, including Apache, PHP and MySQL. Next, we complete the development of the online lending management system step by step.

Create database: First, create a database in MySQL and name it "library".

Create database connection: In the PHP code, we need to make a database connection. Create a file named "db_connect.php" and add the following code:

<?php
 $servername = "localhost";
 $username = "root";
 $password = "";
 $dbname = "library";

 // 创建数据库连接
 $conn = new mysqli($servername, $username, $password, $dbname);

 // 检测连接是否成功
 if ($conn->connect_error) {
     die("连接失败：" . $conn->connect_error);
 }
?>

Copy after login

Create a student registration and login page: Create a file named "register_login.php" and add the following Code:

<!DOCTYPE html>
<html>
<head>
 <title>学生注册和登录</title>
</head>
<body>
 <h1 id="学生注册">学生注册</h1>
 <form action="register.php" method="POST">
     <label>姓名：</label>
     <input type="text" name="student_name" required><br><br>
     <label>账号：</label>
     <input type="text" name="student_username" required><br><br>
     <label>密码：</label>
     <input type="password" name="student_password" required><br><br>
     <input type="submit" name="submit" value="注册">
 </form>

 <h1 id="学生登录">学生登录</h1>
 <form action="login.php" method="POST">
     <label>账号：</label>
     <input type="text" name="student_username" required><br><br>
     <label>密码：</label>
     <input type="password" name="student_password" required><br><br>
     <input type="submit" name="submit" value="登录">
 </form>
</body>
</html>

Copy after login

Create a student registration processing page: Create a file named "register.php" and add the following code:

<?php
 include 'db_connect.php';

 $student_name = $_POST['student_name'];
 $student_username = $_POST['student_username'];
 $student_password = $_POST['student_password'];

 $sql = "INSERT INTO student (student_name, student_username, student_password)
         VALUES ('$student_name', '$student_username', '$student_password')";

 if ($conn->query($sql) === TRUE) {
     echo "注册成功";
 } else {
     echo "注册失败：" . $conn->error;
 }

 $conn->close();
?>

Copy after login

Create a student login processing page: Create a file named "login.php" and add the following code:

<?php
 include 'db_connect.php';

 $student_username = $_POST['student_username'];
 $student_password = $_POST['student_password'];

 $sql = "SELECT * FROM student WHERE student_username = '$student_username' AND student_password = '$student_password'";
 $result = $conn->query($sql);

 if ($result->num_rows > 0) {
     echo "登录成功";
 } else {
     echo "账号或密码错误";
 }

 $conn->close();
?>

Copy after login

So far, we have completed the development of student registration and login functions. Next, you can continue to complete the functions of book management, borrowing management and borrowing record query.

4. Summary
Through the introduction of this article, we have learned how to use PHP to write a simple online lending management system, and provided specific code examples. Online lending management systems can help libraries improve work efficiency and provide better services. In the actual development process, we can further improve the system functions, add book classification, book recommendation and other functions to improve the system's practicality and user experience. I hope this article will be helpful to you in learning PHP programming and developing an online lending management system.
