PHP版本控制系统：高效文档管理

news 2025/8/11 5:23:21

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。

以下是一些视图文件的示例，用于展示用户界面：
