<?php // +---------------------------------------------------------------+ // | File System Class Example Page | // +---------------------------------------------------------------+ // | This example will allow you to list and sort files in the | // | specified directory. Change the ROOT_DIR constant below to | // | browse other directories, but be careful of what you allow to | // | be seen. By using this script you agree that I take no | // | responsibility for site security (or lack thereof) whilst | // | using this script. | // +---------------------------------------------------------------+ // | Authors: Jamie Curnow <jc@jc21.com> | // +---------------------------------------------------------------+ // NOTE: This script is for PHP5 ONLY!
