use think\facade\Route;

    return 'hello,ThinkPHP6!';
});

### 使用方式3: 通过队列的方法

#### 还原数据

~~~
$data["database"]="mysql";
$data["opt"]="import";
$data["filename"]="fastadmin-mysql-20240416184903.sql";
backup_queue($data);
~~~

#### 备份数据/修复表/优化表

~~~
$data["database"]="mysql";
$data["opt"]="backup" //backup,repair,optimize;
$data["table"]=["fa_category","fa_auth_rule"];
backup_queue($data);
~~~

### 使用方式4: 通过命令行

~~~
//进入交互模式进行相关操作
php think backup:choice

//备份整个数据库表结构和表数据
php think backup:database

//还原数据
php think backup:import fastadmin-mysql-20240416184903.sql

//列出所有备份文件
php think backup:list

//在执行本代码中会使用到缓存这里是清理缓存的命令
php think backup:cleanup
~~~

### 使用方式5: 自定义（1.x升级到2.x）

> 1.x和2.x 方法对比

| 1.x                                                          | 2.x                                                          | 描述         |

>  备份表
>
> 1.x  是控制器中将需备份到表结构写到缓存/cookie中，然后根据索引找到表
>
> $tables="数据库表列表"; 
>
> $start= $db->setFile($file)->backup($tables[$id], 0);
>
> 2.x 将需备份到表写到缓存中，无需您来处理，只需要您进行按步骤操作
>
> 第一步将备份到表进行缓存，关键方法： Backup::backupStep1($tables)
>
> 第二步备份表结构和数据，关键方法：Backup::backupStep2($tableIndex,$page),返回page直到page=0 循环结束表和表数据备份完毕
>
> 第三步清理缓存，关键方法Backup::cleanup()
