那么这个具体是干什么的呢？那么这个功能站长朋友们通过自定义扩展变量功能，用户可以自定义公共的程序使用变量，为用户扩展系统带来便利。比如可以增加像系统 $public_r[newsurl]这样的变量，还比如扩展了某个系统模型，需要增加设置项都可以用扩展变量来实现。

下面就做一个简单的例子说明一下：

比如我们要实现模板图片的变量地址，那么就点击该功能，再次点击增加扩展变量，然后就填写我们的变量的信息，如图所示：

然后我们需要调用的时候要怎么调用呢，很简单的就如这样的形式$public_r[‘add_变量名’]可取得变量内容，那么我们这里的变量名是temppicpath，那么完整的调用模式是 $public_r[‘add_temppicpath’]，比如我们要调用模板css目录中style.css，那么调用的模式是这样的：

<link href="<?=$public_r['add_temppicpath']?>css/style.css" rel="stylesheet" type="text/css" />

那么这个就很方面把整个模板都写活了如果改变了路径只需要在扩展变量那里去修改即可。那么这个功能的作用就是这样的。
