Code Igniter User Guide Version 1.5.0


Zip Encoding Class

Code Igniter's Zip Encoding Class classes permit you to create Zip archives.

Initializing the Class

Like most other classes in Code Igniter, the Zip class is initialized in your controller using the $this->load->library function:

$this->load->library('zip');

Once loaded, the Parser library object will be available using: $this->zip

Usage Example

Simple example demonstrating how to compress a file and download it to your desktop.

$name = 'mydata1.txt';
$data = 'A Data String!';
$this->zip->add_data($name, $data);

$name = 'mydata2.txt';
$data = 'Another Data String!';
$this->zip->add_data($name, $data);

$this->zip->download('my_backup.zip'); // Parameter contains name of the downloaded file

If you would like to place your data into a folder just include the directory as part of the filename:

$name = 'myfolder/mydata1.txt';
$data = 'A Data String!';
$this->zip->add_data($name, $data);

$name = 'myfolder/mydata2.txt';
$data = 'Another Data String!';
$this->zip->add_data($name, $data);

$this->zip->download('my_backup.zip'); // Parameter contains name of the downloaded file
