Before you can use any variable, you need to set it to value first. I don't
know where you got these examples from, but I believe the authors presume
that you have initialised the variables somewhere else.
If you are learning php, i suggest you use simpler examples, as these
examples probably assume advanced knowledge. I like the tutorials at
http://devshed.com/ myself.
