PHPCMS本身功能已经很完善，自带的模块可用可不用，松耦合特性使其非常适合企业的二次开发。
PC的默认路由在 phpcms/caches/configs/route.php 中定义，为content模块下index控制器的init方法
一. PC所有模块都在module目录下，与数据表名字相同；
module目录中文件就是控制器，控制器名与文件名相同；
立即学习“PHP免费学习笔记（深入）”；
前台控制器如index.php无须继承任何类，用于前台操作；
后台控制器一般需要继承admin模块的admin类，一旦继承admin就需要权限验证（也可以不继承）。
二. 总结开发后台模块的步骤：
1. 后台访问扩展的模块：
扩展 - 菜单管理 - 添加菜单 - 上级：作为一级菜单（模块名，文件名，方法名）
添加子菜单 - 上级：某个一级菜单（填不存在的模块名，填不存在的文件名，填不存在的方法名）
扩展模块后，需要在v9_module中注册模块！（相当于安装）
2. 创建数据表：
<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. 建立后台的数据模型
<?<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. 建立后台控制器：
<?<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>);

* 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>
