PHP File Not Working

I have my file uploading from software to http://kiis.co.nz/song_update.php but it isn’t displaying anything? Why is this?

The PHP script seems to be working fine as far as I can tell. However, it looks like you’re trying to show an empty data file, which obviously results in an empty list.

What link should I use to send the text from the software? I.e the manual says Fastest Web Hosting Services | Buy High Quality Hosting so mine is setup as http://kiis.co.nz/playing/radiodj.php . To view the current playing song I navigate to http://kiis.co.nz/playing/display.php but nothing is displaying. Is there another address I can use to let the PHP accept the text?
