如果启用安全模式并且无法安装扩展，如何使用PHP解压缩文件？

Question

Are there any PHP-scripts out there that can unzip regular zip-files? The requirements we have is that we must run with safe_mode on and we're not allowed to install any extensions to enable this functionality. Thus, any functionality must be regular php scripts.

Any thoughts?

EDIT: Unfortunately, neither of the posted solution works for us. We may not change the safe_mode requirement unless switching hosts, which is currently not an option.

pclzip.lib.php is a fairly popular and well used php class that is able to extract zip file susing pure php
