CTF-WEB排行榜制作

项目需求：
现在14道题对应有14个flag，我需要使用dockerfile搭建一个简单的，能够实现验证这些题目对应的flag来计分的简单网站（要求页面比较精美） 
前十题设置为10分
11-14题设置为20分
1.	flag{5a3dR7vKpQ9wXyZ2}
2.	flag{8G4hLbNqFcTjMnP6}
3.	flag{3V9sEkYmWuHxDrz1}
4.	flag{J7r2tLqZfNpD4mKs}
5.	flag{B6nQwRvXcT3yUh9P}
6.	flag{qW4eF8gHjK2lO7iU}
7.	flag{M9aZsEdCvFbRtY3N}
8.	flag{2Lp5oIuG7yTqW1rD}
9.	flag{R4vNkSmXzHcJ8wB3}
10.	flag{6dFgHjKl9pOiU7yT}
11.	flag{W3zYcT8rDxV5sQmK}
12.	flag{9PnZtLwEfR6vGhJ4}
13.	flag{7UkXbMqAsHdF2iN1}
14.	flag{yT4jKmP9oLvRgS8e}

创建目录结构命令：

# 创建目录结构与文件
# 切换到工作目录（例如 /root 或 ~/）
mkdir -p ~/ctf && cd ~/ctf# 创建顶层目录和文件
mkdir -p ctf/web
touch ctf/docker-compose.yml
touch ctf/init.sql# 创建 web 子目录下的文件
touch ctf/web/Dockerfile

touch ctf/web/index.php
touch ctf/web/leaderboard.php
touch ctf/web/submit.php
touch ctf/web/style.css
touch ctf/web/db.php
tree ctf

flags.php：题目flag和分值配置（包含前五奖励逻辑支持）

init.sql：MySQL建表与初始化

submit.php：处理flag提交与写入逻辑

leaderboard.php：统计并展示排行榜

index.php：主页面

Dockerfile + docker-compose.yml：构建环境配置

构建和运行命令：

cd ctf
docker-compose build
docker-compose up -d

访问测试：
浏览器打开 http://localhost

常见问题解决：

如果遇到权限问题，在命令前加sudo
如果端口冲突，修改docker-compose.yml中的端口映射为 “8080:80”
清除环境使用：docker-compose down -v
查看日志：docker-compose logs -f

以上命令会：

创建完整的目录结构
生成所有配置文件
构建PHP+Apache镜像
启动MySQL数据库
自动初始化数据库结构
启动网站服务
自动设置好题目flag和评分规则
