Utility method 公共方法

_forward utility method

_forward()公共方法是用来呼叫actions，这可以使我们更容易的在action之间进行传值。
_forward($action, $controller = null, $module = null,  array $params = null)




我们看到_forward()包含四部分，其中三部份是可选的：

• $action (string required): The action to call.
• $controller (string optional): The controller the action is in.
• $module (string optional): The module the controller is in.
• $params (array optional): User parameters to send with the request.

当只提供$action时，方法会在该方法所在的controller里查找该action.

例如：
我们新建一个controller名为 contact:






在index controller里做如下更改：




打开 http://127.0.0.1:8080/index/index 时，会看到：




_redirect() utility method

跟_forward()功能相反。

The _redirect() utility method is in a way the opposite to _forward().
Where _forward() calls an action within the same request, _redirect()  performs an HTTP redirect creating a new request.
redirect() accepts the following arguments:

• $url (string required): The URL to redirect to
• $options (Array Optional)

And the $options can be:

• exit (Boolean): Whether to exit straight away, or not
• prependBase (Boolean): Prepend the base URL, or not
• code (String): The HTTP code to use

By default, _redirect() will do a 302 redirect.
