1、用途
$CATEGORY 是一個二維數組，主要用來保存當前頻道或者模塊所以欄目的基本配置信息。
2、如何設置
您可以登錄後台進入模塊或者頻道的欄目管理，然後在線修改任何一個欄目設置即可改變參數值。修改欄目參數設置系統會更新phpcms_category裡相應記錄的值，同時把各欄目基本信息數組緩存到 ./data/cache/category_頻道ID.php ，每次訪問有欄目的模塊或頻道時系統會自動加載其欄目基本配置信息。
3、作用范圍
$CATEGORY 數組是系統默認加載的，可以在當前模塊或頻道的任何php文件和模板中調用。
如何加載另一個模塊或者頻道的欄目信息呢？
$product_cats = cache_read('categorys_product.php'); //加載product模塊欄目信息的方法
$cats_1 = cache_read('categorys_1.php'); //加載頻道ID為1的欄目信息的方法
4、數組元素
下面以默認安裝的文章頻道為例
