| <h1>Zip Encoding Class</h1> | |
| <p>Code Igniter's Zip Encoding Class classes permit you to create Zip archives.</p> | |
| <h2>Initializing the Class</h2> | |
| <p>Like most other classes in Code Igniter, the Zip class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p> | |
| <code>$this->load->library('zip');</code> | |
| <p>Once loaded, the Parser library object will be available using: <dfn>$this->zip</dfn></p> | |
| <h2>Usage Examples</h2> | |
| <p>Simple example demonstrating how to compress a file and download it to your desktop.</p> | |
| <code> | |
| $name = 'mydata1.txt';<br /> | |
| $data = 'A Data String!';<br /> | |
| $this->zip->add_data($name, $data);<br /> | |
| <br /> | |
| $name = 'mydata2.txt';<br /> | |
| $data = 'Another Data String!';<br /> | |
| $this->zip->add_data($name, $data);<br /> | |
| <br /> | |
| $this->zip->download('my_backup.zip'); // Parameter contains name of the downloaded file | |
| </code> | |
| <p>If you would like to place your data into a folder just include the directory as part of the filename:</p> | |
| <code> | |
| $name = 'myfolder/mydata1.txt';<br /> | |
| $data = 'A Data String!';<br /> | |
| $this->zip->add_data($name, $data);<br /> | |
| <br /> | |
| $name = 'myfolder/mydata2.txt';<br /> | |
| $data = 'Another Data String!';<br /> | |
| $this->zip->add_data($name, $data);<br /> | |
| <br /> | |
| $this->zip->download('my_backup.zip'); // Parameter contains name of the downloaded file | |
| </code> | |
| <p>You can also pass your file data as an array:</p> | |
| <code> | |
| $data = array(<br /> | |
| 'myfolder/mydata1.txt' => 'A Data String!',<br /> | |
| 'myfolder/mydata2.txt' => 'Another Data String!'<br /> | |
| );<br /> | |
| <br /> | |
| $this->zip->add_data($data);<br /> | |
| <br /> | |
| $this->zip->download('my_backup.zip'); // Parameter contains name of the downloaded file | |
| </code> | |
