系统功能说明
这个PHP版本控制系统实现了以下核心功能：
1. 用户认证与权限管理
- 用户注册、登录和登出
- 三级权限系统：管理员（admin）、编辑者（editor）和查看者（viewer）
- 基于角色的访问控制（RBAC）
2. 仓库管理
- 创建新仓库
- 查看仓库列表和详情
- 仓库统计信息（提交数、分支数、贡献者）
3. 文档版本控制
- 上传文档到仓库
- 查看文档历史版本
- 检索特定版本的文档内容
- 类似Git的提交机制
4. 分支管理
- 创建新分支
- 查看分支列表
- 合并分支到主分支
5. 权限控制
- 仓库级别的权限控制
- 基于用户角色的操作限制
安装与使用
- 创建数据库并运行
install.php初始化数据库结构 - 配置
config.php中的数据库连接信息 - 将所有文件上传到Web服务器
- 访问系统首页进行注册和登录
- 管理员可以创建仓库，用户可以上传文档并管理版本
这个系统提供了完整的文档版本控制功能，适合团队协作管理文档，支持权限分级和版本历史追踪。
