thinkPHP uses pclzip package to back up mysql database

The example in this article describes how thinkPHP uses pclzip packaging to back up mysql database. Share it with everyone for your reference, the details are as follows:

PclZip introduction PclZip library can compress and decompress compressed files in Zip format (WinZip, PKZIP); and can process such files, including generating compressed files and listing compressed files. The contents of the file, decompressed files, etc.

Database backup is a very important thing. There are many ways to back up, some of which are directly backed up through vps, and some are backed up through phpmyadmin. The editor thinks this is troublesome and the backed up .sql file is too large and takes up a certain amount of space. So use pclzip to compress the sql file, which saves some space. The editor has written the database backup code before and will not repeat it here. The official download address of Pclzip is: http://www.phpconcept.net/pclzip/pclzip-downloads (the latest version 2-8-2).

Look for file_put_contents in the DatabaseAction.class.php file and add the following code below

import("ORG.Util.PclZip");
$archive = new PclZip('./data/'.date("y-m-d").'.zip');
$v_list = $archive->create($dir);
if(file_exists($dir)&&$v_list != 0)
{
$this->success("备份成功&&压缩成功");
}else
{
die("Error : ".$archive->errorInfo(true));
$this->error("备份失败");
}

And delete the original if judgment in the original DatabaseAction.class.php
