My biggest : trouble right now is what should be the classes and what should be the : methods.
Objects should try to model a real thing. A thing may have properties (e.g. weight, color, dimensions, temperature, gender, age) and/or states (e.g. solid/liquid/gas, running/ready/waiting, eating/sleeping/working); properties are stored in instance variables. And the thing can do tasks or have tasks done to them; these tasks are your methods. Here's a simple exercise you can do: make a "watch" class that models a real watch. You can get the current time from a watch; and you can also set the watch's time. This class should have 3 methods (i.e. 2 methods and 1 constructor) and 1 instance variable. If you use Unix timestamps, this should be really short (maybe around 10 lines of PHP code). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
