以下是引用片段：

//语言包路径
if (!isset($_COOKIE['i_im_language'])) {
        setcookie("i_im_language",$langPackagePara,time()+3600*24,"/");
}
$im_language = $_COOKIE['i_im_language']?$_COOKIE['i_im_language']:$langPackagePara;
$langPackageBasePath="langpackage/".$im_language."/";
//语言文件
require_once($langPackageBasePath."language.php");
