# add a file named 'some_image.jpg' from a local file 'path/to/image.jpg'
$zip->addFileFromPath('some_image.jpg', 'path/to/image.jpg');

# add a file named 'goodbye.txt' from an open stream resource
$fp = tmpfile();
fwrite($fp, 'The quick brown fox jumped over the lazy dog.');

# finish the zip stream

You can also add comments, modify file timestamps, and customize (or disable) the HTTP headers. It is also possible to specify the storage method when adding files, the current default storage method is 'deflate' i.e files are stored with Compression mode 0x08. See the class file for details.
