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
