Functions, Classes and Objects
Most people seem to think they first need to tell you why you should bother with all this before they tell you how to do it, but i'm not not going to do that. you certainly do not need to write and use classes in php, but if you are here then chances are you want to know some more about it. if you read this and decide that you have no reason to write your own classes, then you are probably right and i will not try to change your mind, but hopefully the reason will be something other than not kno
