Archives can be downloaded to your -desktop or saved to a directory.</p> - - -<h2>Initializing the Class</h2> -<p>Like most other classes in CodeIgniter, 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 Zip library object will be available using: <dfn>$this->zip</dfn></p> - - -<h2>Usage Example</h2> - -<p>This example demonstrates how to compress a file, save it to a folder on your server, and download it to your desktop.</p> - -<code> -$name = 'mydata1.txt';<br /> -$data = 'A Data String!';<br /> -<br /> -$this->zip->add_data($name, $data);<br /> -<br /> -// Write the zip file to a folder on your server. Name it "my_backup.zip"<br /> -$this->zip->archive('/path/to/directory/my_backup.zip'); -<br /><br /> - // Download the file to your desktop. Name it "my_backup.zip"<br /> -$this->zip->download('my_backup.zip'); -</code> - -<h1>Function Reference</h1> - -<h2>$this->zip->add_data()</h2> - -<p>Permits you to add data to the Zip archive. The first parameter must contain the name you would like -given to the file, the second parameter must contain the file data as a string:</p> - -<code> -$name = 'my_bio.txt';<br /> -$data = 'I was born in an elevator...';<br /> -<br /> -$this->zip->add_data($name, $data); -</code> - -<p>You are allowed multiple calls to this function in order to -add several files to your archive. Example:</p> - -<code> -$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, $data);<br /> -</code> - -<p>Or you can pass multiple files using an array:</p> - -<code> -$data = array(<br /> - 'mydata1.txt' => 'A Data String!',<br /> - 'mydata2.txt' => 'Another Data String!'<br /> - );<br /> -<br /> -$this->zip->add_data($data);<br /> -<br /> -$this->zip->download('my_backup.zip'); -</code> - -<p>If you would like your compressed data organized into sub-folders, include the path as part of the filename:</p> - -<code> -$name = '<kbd>personal/</kbd>my_bio.txt';<br /> -$data = 'I was born in an elevator...';<br /> -<br /> -$this->zip->add_data($name, $data); -</code> - -<p>The above example will place <dfn>my_bio.txt</dfn> inside a folder called <kbd>personal</kbd>.</p> - - -<h2>$this->zip->add_dir()</h2> - -<p>Permits you to add a directory. Usually this function is unnecessary since you can place your data into folders when -using <dfn>$this->zip->add_data()</dfn>, but if you would like to create an empty folder you can do so. Example:</p> - -<code>$this->zip->add_dir('myfolder'); // Creates a folder called "myfolder"</code> - - - -<h2>$this->zip->read_file()</h2> - -<p>Permits you to compress a file that already exists somewhere on your server. Supply a file path and the zip class will -read it and add it to the archive:</p> - -<code> -$path = '/path/to/photo.jpg';<br /><br /> -$this->zip->read_file($path); -<br /><br /> - // Download the file to your desktop. Name it "my_backup.zip"<br /> -$this->zip->download('my_backup.zip'); -</code> - -<p>If you would like the Zip archive to maintain the directory structure of the file in it, pass <kbd>TRUE</kbd> (boolean) in the -second parameter. Example:</p> - - -<code> -$path = '/path/to/photo.jpg';<br /><br /> -$this->zip->read_file($path, <kbd>TRUE</kbd>); -<br /><br /> - // Download the file to your desktop. Name it "my_backup.zip"<br /> -$this->zip->download('my_backup.zip'); -</code> - -<p>In the above example, <dfn>photo.jpg</dfn> will be placed inside two folders: <kbd>path/to/</kbd></p> - - - -<h2>$this->zip->read_dir()</h2> - -<p>Permits you to compress a folder (and its contents) that already exists somewhere on your server. Supply a file path to the -directory and the zip class will recursively read it and recreate it as a Zip archive. All files contained within the -supplied path will be encoded, as will any sub-folders contained within it. Example:</p> - -<code> -$path = '/path/to/your/directory/';<br /><br /> -$this->zip->read_dir($path); -<br /><br /> - // Download the file to your desktop. Name it "my_backup.zip"<br /> -$this->zip->download('my_backup.zip'); -</code> - -<p>By default the Zip archive will place all directories listed in the first parameter inside the zip. If you want the tree preceding the target folder to be ignored -you can pass <kbd>FALSE</kbd> (boolean) in the second parameter. Example:</p> - -<code> -$path = '/path/to/your/directory/';<br /><br /> -$this->zip->read_dir($path, FALSE); -</code> - -<p>This will create a ZIP with the folder "directory" inside, then all sub-folders stored correctly inside that, but will not include the folders <samp>/path/to/your</samp>.</p> - - - - -<h2>$this->zip->archive()</h2> - -<p>Writes the Zip-encoded file to a directory on your server. Submit a valid server path ending in the file name. Make sure the -directory is writable (666 or 777 is usually OK). Example:</p> - -<code>$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip</code> - - -<h2>$this->zip->download()</h2> - -<p>Causes the Zip file to be downloaded from your server. The function must be passed the name you would like the zip file called. -Example:</p> - -<code>$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"</code> - -<p class="important"><strong>Note:</strong> Do not display any data in the controller in which you call this function since it sends various server headers -that cause the download to happen and the file to be treated as binary.</p> - - -<h2>$this->zip->get_zip()</h2> - -<p>Returns the Zip-compressed file data. Generally you will not need this function unless you want to do something unique with the data. -Example:</p> - -<code> -$name = 'my_bio.txt';<br /> -$data = 'I was born in an elevator...';<br /> -<br /> -$this->zip->add_data($name, $data);<br /><br /> - -$zip_file = $this->zip->get_zip(); -</code> - - -<h2>$this->zip->clear_data()</h2> - -<p>The Zip class caches your zip data so that it doesn't need to recompile the Zip archive for each function you use above. -If, however, you need to create multiple Zips, each with different data, you can clear the cache between calls. Example:</p> - -<code> -$name = 'my_bio.txt';<br /> -$data = 'I was born in an elevator...';<br /> -<br /> -$this->zip->add_data($name, $data);<br /> -$zip_file = $this->zip->get_zip();<br /> -<br /> -<kbd>$this->zip->clear_data();</kbd> -<br /><br /> - -$name = 'photo.jpg';<br /> -$this->zip->read_file("/path/to/photo.jpg"); // Read the file's contents<br /> -<br /><br /> -$this->zip->download('myphotos.zip'); -</code> - - - - - - - - - - - - - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="xmlrpc.html"> XML-RPC Class</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="caching.html">Caching Class</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>
