Role: Example script
Content type: text/plain
Description: Version 2.0 for this package. The entire structure have been reworked, and it is now using namespace, meaning that PHP 5.3 is now required as a minimum. See the examples in the legacy folder to see how you can easily migrate to the new structure. Most notable new function added is appendZip, to merge the content of an existing Zip file into the current one without re-compression, using the PHP Zip Merge package, also available here on PHPClasses.

// To use the new namespaces, you need a bootstrapper/autoloader, examples are provided here.

// new \PHPZip\Zip\File\Zip(
