class.Forum.php

<?php

/* A class representing a single Forum. Each Forum contains a number of topics.
In other words, it is the largest category.

Each forum has a forumId, a forum name, a description, a number of posts and a
number of topics.

The noOfTopics and noOfPosts are cached here for performance reasons instead of
recounting the number of posts each time it is required.

The object is constructed from a string in the following format:
forumId~forumName~description~noOfTopics~noOfPosts

Each forum is a line in a file:
db/forumList.dat
