使用laravel下载数据库架构文件（.sql文件）

Schenario： 我假设我有一个名为myDataBase的数据库 2假设myDataBase有一些表，如A、B、C、D

---

3我必须从名为myDataBase的数据库中下载表A、B的模式，希望您已经完成了项目所有表的迁移。如果您使用的是xampp服务器，则转到并选择您的数据库，然后转到顶部选项卡栏上的“导出”选项卡，只需使用“转到”按钮导出即可。欢迎使用StackOverflow。请访问，采取的，看看什么和。做一些研究，搜索相关话题等；如果您遇到问题，请发布您的尝试，记录输入和预期输出。如果您没有得到任何相关信息，那么您的问题太宽泛，很可能很快就会结束，这不是一个代码编写服务，正如上面的评论所述-阅读并创建一个由PhpMyAdmin GUI编写的“我知道它”，但我希望在运行时使用laravel或Php5+代码下载它
