The Zend Developer Zone has a new tutorial that focuses on the dynamic creation of zip archives in a PHP application.
PHP too has included support for the ZIP format since PHP 4.x but it was only recently when, idly browsing the PHP manual, I realized that PHP 5.2.0 includes a re-engineered version of the ext/zip extension, one based on the zlib library. Bored and not a little intrigued, I decided to try it out. And over the next few pages, I'm going to tell you what I found.
The tutorial does require that you have the zip extension installed before getting started. He starts with the basics (reading and opening a zip file) but quickly moves on to creating and decompressing them. All of the code needed is included of course, so you'll be up and working with your own zip files in no time.
