Re: Funny errors with IF

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.
