🗣 Wd提问: php预约挂号系统源码

🤖 Ai回答:
PHP预约挂号系统是一种基于Web的应用程序，用于帮助医院或诊所管理患者的预约和挂号。这类系统通常包括用户注册、登录、查看医生信息、选择医生和时间、提交预约请求等功能。以下是一个简单的PHP预约挂号系统的源码示例，供你参考。

1、系统结构

/clinic-appointment
│
├── index.php // 首页
├── login.php // 登录页面
├── register.php // 注册页面
├── dashboard.php // 用户仪表盘
├── doctors.php // 医生列表
├── appointment.php // 预约页面
├── submit_appointment.php // 提交预约请求
├── logout.php // 登出
├── db.php // 数据库连接
└── styles.css // 样式表

2、数据库设计

假设我们使用MySQL数据库，以下是数据库表的设计：

`users` 表（用户表）
sql
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(50) NOT NULL UNIQUE,
password VARCHAR(255) NOT NULL,
email VARCHAR(100) NOT NULL UNIQUE,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

`doctors` 表（医生表）
sql
CREATE TABLE doctors (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100) NOT NULL,
specialty VARCHAR(100) NOT NULL,
available_slots TEXT
);

`appointments` 表（预约表）
sql
CREATE TABLE appointments (
id INT AUTO_INCREMENT PRIMARY KEY,
user_id INT NOT NULL,
doctor_id INT NOT NULL,
appointment_date DATETIME NOT NULL,
status ENUM('pending', 'confirmed', 'cancelled') DEFAULT 'pending',
FOREIGN KEY (user_id) REFERENCES users(id),
FOREIGN KEY (doctor_id) REFERENCES doctors(id)
);

3、源码示例

`db.php` 数据库连接
php
<?php
$host = 'localhost';
$dbname = 'clinic_appointment';
$username = 'root';
$password = '';

try {
$pdo = new PDO(mysql:host=$host;dbname=$dbname, $username, $password);
$pdo-setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
die(Connection failed: 、$e-getMessage());
