(About the author)
 
     This code can be used as a universal index file. It will create links to any files within it's current directory. The only customization needed is in the $allowedFiles array. This array contains the extenstions you want to allow (duh). I created this for something I was doing for work, and thought I would share it with the world.

I'm fairly new to PHP and needed a chunk of code that does exactly what this script does. I have looked around for many hours trying to solve this problem. This is last piece I was missing from a total solution. Deperately needed the array handling and the hyperlinking! Thanks a bunch.

To bad the code only works on Apache because of the $SCRIPT_FILENAME variable.
