Pierre-Alain Joye has posted about the latest update to his Zip PECL package today:

This release fixes two small issues, a leak happening on error and a bug in extractTo. Empty directories were not created recursively, for example an entry like "test/emptydir", only the "test" directory was created.

This latest download is here and the homepage for the project is over on this PECL page (as well as details on what the package can do and documentation of all of its features).
