PHP to do the project in English and Chinese switch, how to quickly achieve

This is the method that I summarize when I am doing the project, of course, if you have a better way, you can share it with me.

Generally I would suggest to build 2 documents, a Chinese one in English

On the View page:

              ' CN '));?> "> Chinese" en ")        ?>" >english      

On the Controller page:

$page = ' newexhibitors ', if (isset ($_get[' language ')) {   if ($_get[' language ']== ' cn ') {       $_session[' lan '] = ' cn ' ;       $title = ' test ';       Require APP::TPL (' newexhibitors ');   } else if ($_get[' language ']== ' en ') {       $_session[' lan '] = ' en ';       $title = ' Test ';       Require APP::TPL (' en_newexhibitors ');}   } else{    if ($_session[' LAN ')} {       if ($_session[' LAN ']== ' CN ') {            $title = ' Test ';            Require APP::TPL (' newexhibitors ');       } else{            $title = ' Test ';            Require APP::TPL (' en_newexhibitors ');       }    } else{       $_session[' LAN ']= ' CN ';       $title = ' test ';       Require APP::TPL (' newexhibitors ');}    }

This code implementation of the effect, click on the "Chinese/English" text switch, automatically on the current page to switch
