_throw($msg, $code)

抛出异常.

_redirect($url)

HTTP 301 跳转到指定的 URL, 该函数除了不能放在 try 代码块中外, 可以放在任何地方.

_url($url, mixed $param=array())

所有使用 iphp 框架的应用, 都应该使用 `_url()` 或者 `_action()` 函数来生成链接(URL), 而不是手动拼接字符串.

若 `$url` 是相对路径且以 `/view|list` 结尾, 则会生成__特殊__ URL. 例如:

_url('/book/view', array('id'=>1)) 返回 http://localhost/book/1
_url('/book/list', array('page'=>3)) 返回 http://localhost/book?page=3

若 `$param` 是 Model 的实例, 则其 id 会被取出来作为 URL 参数.

若 `$param` 是数组, 则该数组作为 URL 的参数.

_action($act, mixed $m=null, $module='')

若 `$url` 以 `/view|list` 结尾, 则会生成__特殊__ URL. 如果不指定 `$module`, 则使用当前 controller 的 module.

另外, iphp 还内置了一些常用函数, 用于简便地生成 URL:

* _new_url()
* _save_url()
* _list_url()
* _view_url($model)
* _edit_url($model)

_render($view_name)

默认 iphp 会寻找与当前 controller 中的 action(函数名)同名的 view 来渲染. 如, 当前的 action 函数是 `find()`, 那么名字为 `find.tpl.php` 的视图文件将会被渲染.

但你可以通过 `_render()` 函数修改视图文件的名字.
