DirPHP

DirPHP is a quick tool for a) displaying all files in its same directory and subdirectories and color coding and organizing by several factors, b) displaying other PHP files' source code (instead of simply linking to them, allowing the user to see the code non-parsed by the server), and c) performing simple file uploads to the directory. DirPHP is extremely simple to install and use. No configuration is required, and the script is contained in a single PHP file, allowing the program to simply be placed in a webserver directory and have instant functionality.
