1、用途
$CATEGORY 是一个二维数组，主要用来保存当前频道或者模块所以栏目的基本配置信息。
2、如何设置
您可以登录后台进入模块或者频道的栏目管理，然后在线修改任何一个栏目设置即可改变参数值。修改栏目参数设置系统会更新phpcms_category里相应记录的值，同时把各栏目基本信息数组缓存到 ./data/cache/category_频道ID.php ，每次访问有栏目的模块或频道时系统会自动加载其栏目基本配置信息。
3、作用范围
$CATEGORY 数组是系统默认加载的，可以在当前模块或频道的任何php文件和模板中调用。
如何加载另一个模块或者频道的栏目信息呢？
$product_cats = cache_read('categorys_product.php'); //加载product模块栏目信息的方法
$cats_1 = cache_read('categorys_1.php'); //加载频道ID为1的栏目信息的方法
4、数组元素
下面以默认安装的文章频道为例

本文档主要讲述的是j2me3D游戏开发简单教程； 如今，3D图形几乎是任何一部游戏的关键部分，甚至一些应用程序也通过用3D形式来描述信息而获得了成功。如前文中所述，以立即模式和手工编码建立所有的3D对象的方式进行开发速度很慢且很复杂。应用程序中多边形的所有角点必须在数组中独立编码。在JSR 184中，这称为立即模式。希望本文档会给有需要的朋友带来帮助；感兴趣的朋友可以过来看看
