Well, somehow I managed to let more than a month slip by without getting this post up. Between being quite busy for a lot of the time, and a bit of procrastination it was easy to fall behind. I've been making progress off and on through PHP and MySQL for Dynamic Web Sites, but with the extremely hot weather in Toronto lately, it has been difficult to get any reading done on the subway sometimes.
Variables are the subject of this long delayed post. Variables are used in PHP in much the same way that they are in virtually any other major scripting or programming language. Variables use in PHP is fairly informal. A variable's name must start with a dollar sign and be followed with a letter or underscore (e.g. $variable); beyond that it can be called more or less whatever you want. Unlike in some other languages, variables can be created on the fly, and don't have to be declared or initialized beforehand.
