I'm learning PHP and would appreciate it if you explain what you are talking about here. Please be clear and help dummies. I'm sure there are a lot of guys like me out there who have heard about classes but would like to know how you do it in a case like this.

This is an interesting and useful piece of code. However, I know nothing about classes so I cannot help you with that bit. Sorry!-Athleone

A class is basically a piece of code that can be stored as an object in memory. It can be very useful if you want to be able to store a variety of data in one variable, and you want to modify the data easily by running methods.
