Read a directory and export pretty directory list

/ Published in: PHP

This script reads a directory of files. After reading the directory specified it outputs the directory files. Upon output, supplied functions manipulate each filename and format it to make the output filename look better. e.g.: instead of output being 'my-good-looking-file.txt' it would look like 'My Good Looking File'.
