Thinkphp method of using Pclzip to pack up MySQL database _php instance

The example in this article describes how thinkphp uses Pclzip to pack up a MySQL database. Share to everyone for your reference, specific as follows:

Pclzip describes the Pclzip Library's ability to compress and decompress zip formats (WINZIP, PKZIP), and to process such files, including producing compressed files, listing the contents of compressed files, and extracting files, etc.

Database backup is a very important thing, the way of backup is also a lot of the direct backup through the VPS, and some through the phpMyAdmin data for backup. Small knitting think these should be troublesome and backup good. sql files are too large to occupy a certain amount of space. So the SQL file is compressed with Pclzip, which saves a bit of space. Before the small series has written a database backup code here will not repeat, pclzip official download Address: Http://www.phpconcept.net/pclzip/pclzip-downloads (the latest version of 2-8-2).

Look for file_put_contents in the DatabaseAction.class.php file 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 ("Backup succeeded && compression succeeded");
} else
{
die ("Error:". $archive->errorinfo (True));
$this->error ("Backup Failed");
}

And the original DatabaseAction.class.php Central Plains have if judge delete
