tp5-databackup's Introduction

使用composer进行安装

    composer require tp5er/tp5-databackup
	//或
    composer require tp5er/tp5-databackup dev-master

使用composer update进行安装

    "require": {
        "tp5er/tp5-databackup": "dev-master"
    },
    //或
    "require": {
        "tp5er/tp5-databackup": "1.0.0"
    },

引入类文件

use \tp5er\Backup;

参数说明

$start:无论是备份还是还原只要一张表备份完成$start就是返回的0
$file :sql文件的名字,下面有名字命名规范,如果名字命令不规范,在展示列表中就会出现错误

配置文件

$config=array(
    'path'     => './Data/',//数据库备份路径
    'part'     => 20971520,//数据库备份卷大小
    'compress' => 0,//数据库备份文件是否启用压缩 0不压缩 1 压缩
    'level'    => 9 //数据库备份文件压缩级别 1普通 4 一般  9最高
);

实例化

 $db= new Backup($config);

文件命名规则,请严格遵守(温馨提示)

$file=['name'=>date('Ymd-His'),'part'=>1]

数据类表列表

return $this->fetch('index',['list'=>$db->dataList()]);

备份文件列表

  return $this->fetch('importlist',['list'=>$db->fileList()]);

备份表

 $tables="数据库表1";
 $start= $db->setFile($file)->backup($tables[$id], 0);

导入表

 $start=0;
 $start= $db->setFile($file)->import($start);

删除备份文件

    $db->delFile($time);

下载备份文件

    $db->downloadFile($time);

修复表

    $db->repair($tables)

优化表

    $db->optimize($tables)

大数据备份采取措施1

如果备份数据比较大的情况下,需要修改如下参数
//默认php代码能够申请到的最大内存字节数就是134217728 bytes,如果代码执行的时候再需要更多的内存,根据情况定义指定字节数
memory_limit = 1024M
//默认php代码申请到的超时时间是20s,如果代码执行需要更长的时间,根据代码执行的超时时间定义版本运行超时时间
max_execution_time =1000

大数据备份采取措施2

    自由设置超时时间。支持连贯操作,该方法主要使用在表备份和还原中,防止备份还原和备份不完整
    //备份
    $time=0//表示不限制超时时间,直到程序结束,(慎用)
    $db->setTimeout($time)->setFile($file)->backup($tables[$id], 0);
    //还原
    $db->setTimeout($time)->setFile($file)->import($start);
