Not the prettiest thing going, but It was my first time [strike]stealing[/strike] writing PHP code and setting up PHP on my Apache server.
Bad side is, my cool XML idea doesn't work because all the individual elements have to be inside one master element. Appending lines won't work if I have to insert them before the last line.
So I'm going to have to figure out what other format to use so I can actually read what I put in. And password protect the input page so I don't have to worry about people finding it and trashing it.
