1.plan
1.1 why write this blog
because i want to share my experience for your.
1.2 what purpose
my zend framework 2 index will detect user browser language,and intelligent redirect to other uri ex: xxx/controller/action/uilang/data locale id/other params.
2. do
2.1 designer draft
a. the detect user browser is implement in project/Application/view/application/index/index.phtml view file.it will used user browser header value $uilang = $_SERVER["HTTP_ACCEPT_LANGUAGE"].then give my mysql locale table,select localeid from localetable where locale=$uilang.and redirect to default target url.
b.default target url page will parse uilang and localeid param,when process data or redirect other uri,can used these value.
c.look up zend framework 2 route mechanism,and finished these step.

3.check
when i access default uri:http：// localhost/projectname/
then it redirect to http：// localhost/projectname/rank/internet/zh_CN/2
next timer,when i want to redirect to other url in rank/index view,then get $uilang = $this->controller->params(‘uilang’,’en_US’) and $lid = $this->controller->params(‘lid,1); ,and get new other target uri by code:
$this->controller->plugin('url')->fromRoute('application/image',array('q' => $item['key'],'uilang' => $uilang))
4.action
interflow with me,wait for improve,
5.last
thanks!
