PHPCMS本身功能已經很完善，自帶的模組可用可不用，鬆散耦合特性使其非常適合企業的二次開發。
PC的預設路由在 phpcms/caches/configs/route.php 中定義，為content模組下index控制器的init方法
一. PC所有模組都在module目錄下，與資料表名字相同；
module目錄中檔案就是控制器，控制器名稱與檔案名稱相同；
前台控制器如index.php無須繼承任何類，用於前台操作；
後台控制器一般需要繼承admin模組的admin類，一旦繼承admin就需要權限驗證（也可以不繼承）。
二. 總結開發後台模組的步驟：
1. 後台存取擴充的模組：
擴充 - 選單管理 - 新增選單 - 上級：作為一級選單（模組名，檔案名，方法名）
新增子選單 - 上級：某個一級選單（填不存在的模組名，填不存在的檔案名稱，填入不存在的方法名稱）
擴充模組後，需要在v9_module中註冊模組！ （相當於安裝）
2. 建立資料表：
<span>create</span> <span>table</span><span> v9_link(
.........</span><span>
)engine</span><span>=</span>myisam <span>default</span> charset<span>=</span><span>'</span><span>utf8</span><span>'</span><span>;</span>
3. 建立後台的資料模型
<?<span>php<br /></span><span>defined</span>('IN_PHPCMS') or <span>exit</span>('No permiss resources.'<span>);
pc_base</span>::load_sys_class('model', '', 0<span>);
</span><span>class</span> link_model <span>extends</span><span> model {
</span><span>function</span><span> __construct() {
</span><span>$this</span>->db_config = pc_base::load_config('database'<span>);
</span><span>$htis</span>->db_setting = 'default'<span>;
</span><span>$this</span>->table_name = 'link'<span>;
parent</span>::<span>__construct();
}
}
</span><span>/*</span><span>*
* 几点注意：
* 1. PC的数据模型基本是鸡肋，只是指定了数据库设置和对应的表名，非彻底的MVC，直接复制一份修改即可。
* 2. 此模型一般在控制器构造方法调用。<br> </span><span>*/</span>
4. 建立後台控制器：
<?<span>php
</span><span>/*</span><span>*
* 后台友情链接，完整CURD
</span><span>*/</span>
<span>defined</span>('IN_PHPCMS') or <span>exit</span>('No permission resources.'<span>);

* 几点注意：
* 1. 作为一款产品，你可以感受到它程序的严谨性，照着做。
* 2. 操作数据类和其它系统类均在 libs/classes/ 中，数据模型基类model.class.php通过数据库工厂类作为抽象层调用操作数据库的方法。
* 3. 查询所有为listinfo, 单条信息为get_one, 增加为insert， 修改为update。
* 4. 提示消息为系统公共函数showmessage()，在 libs/functions/global.func.php 中。
* 5. L()方法为语言处理函数，将读入语言包，根据后台配置显示英文/中文, 同样是系统公共函数，<br> * 6. 加载后台模板 include $this->admin_tpl(""); 这是admin模块下admin.class.php类的方法<br> * <www.Chenwei.ws>
</span><span>*/</span>
5. 建立後台範本檔案
後台範本檔案都在 modules/link/templates 下，檔案名稱統一以「 .tpl.php」結尾

* 几点注意：
* 1. 后台模板是混编风格，由于在后台控制器中总是最后调用模板，所以系统库和函数以及变量总是可用的。
* 2. 模板底部可以写一些自己的JS操作函数。
