本文实例讲述了TP5框架实现的数据库备份功能。分享给大家供大家参考，具体如下：

1、效果图

TP5框架实现的数据库备份功能示例

2、下载扩展类（ \extands\org\Baksql.php）

3、在 \public\static 里新建一个data 文件夹用来存放 .sql 的文件

4、使用方法

controller

<?php
namespace app\index\controller;
 
use think\Controller;
 
class Backup extends Controller
{
 //数据库备份
 public function bak(){
  $type=input("tp");
  $name=input("name");
  $sql=new \org\Baksql(\think\Config::get("database"));
  switch ($type)
  {
   case "backup": //备份
    $info = $sql->backup();
    $this->success("$info",'index/backup/bak');
    break;
   case "dowonload": //下载
    $info = $sql->downloadFile($name);
    $this->success("$info",'index/backup/bak');
    break;
   case "restore": //还原
    $info = $sql->restore($name);
    $this->success("$info",'index/backup/bak');
    break;
   case "del": //删除
    $info = $sql->delfilename($name);
    $this->success("$info",'index/backup/bak');
    break;
   default: //获取备份文件列表
    return $this->fetch("bak",["list"=>$sql->get_filelist()]);
  }
 }
}
