如何使用PHP会话和cookie保留语言状态

I have this in my index.php:

<?php include_once 'file.php' ?> then I have <html> some content </html>

and I have this in file.php:

<?php
session_start();
header('Cache-control: private');

if(isSet($_GET['lang']))
{
$lang = $_GET['lang'];

$_SESSION['lang'] = $lang;

setcookie("lang", $lang, time() + (3600 * 24 * 30));
}
else if(isSet($_SESSION['lang']))
{
$lang = $_SESSION['lang'];
}
else if(isSet($_COOKIE['lang']))
{
$lang = $_COOKIE['lang'];
}
else
{
$lang = 'en';
}

switch ($lang) {
  case 'en':
  $lang_file = 'lang.en.php';
  break;

  case 'de':
  $lang_file = 'lang.de.php';
  break;

  case 'es':
  $lang_file = 'lang.es.php';
  break;

  default:
  $lang_file = 'lang.en.php';

}

include_once 'languages/'.$lang_file;
?>

I have those 3 files, I mean lang.en.php an so on...

and it doesn't work, my page is empty, no text, why? What's wrong?

lang.en.php contains

<?php


$h1 ="HOME";
$h2 ="ABOUT US";
$h3 ="CONTACT";
$h4 ="FAQ";

$txt1 = "Here goes txt,Here goes txt,Here goes txt,Here goes txt,
         Here goes txt,Here goes txt,Here goes txt,Here goes txt,
         Here goes txt, Here goes txt,Here goes txt,Here goes txt.";
?>

I don't know what's wrong with this... What should I change? Can someone help me. Thanks.

    You are not printing anything except some HTML. To see the contents of the strings in your lang.en.php's files, you'll need to output them using an echo language construct.

    <?php
    echo $txt1;
    ?>
    

    would output:

    Here goes txt,Here goes txt,Here goes txt,Here goes txt,
    Here goes txt,Here goes txt,Here goes txt,Here goes txt,
    Here goes txt, Here goes txt,Here goes txt,Here goes txt.
