This toolkit is written in PHP and implemented as a class, suitable for use in any PHP-based application and accessible via standard OO techniques.
PHP comes with a full-featured file and directory manipulation API that allows you (among other things) to view and modify file attributes, read and list directory contents, alter file permissions, retrieve file contents into a variety of native data structures, and search for files based on specific patterns. This file manipulation API is both powerful and flexible - two characteristics that will endear it to any developer who's ever had to work with file manipulation commands.
