这篇文章主要介绍Laravel中如何使用Migrations，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

Laravel：使用Migrations

1、首先利用artisan创建一个可迁移的数据表模板，该命令运行后会在database/migrations目录下生成一个文件

php artisan make:migration create_fees_count_table --create=fees_count

2、生成的文件包含up和down两个方法，其中up中是包含了添加表，添加列，添加索引等等一切的描述，down比较简单，就是删除表，当然里面还可以有一些其他逻辑

3、up中支持的数据表列类型，做个备注，暂时不做翻译
