looping through a directory to get the filenames

ok, so tonight I decided to learn how to loop through a directory and output all the filenames that are found in a directory. This would be helpful to create lots of pages and they would automatically be updated into the main index.php file. It's currently working at http://www.thebrookchurch.com/test_php/

So that's cool. Now I need to be able to turn them into hyperlinks automatically so they can be clicked......to work on that.
