Redirect User Depending on Language

I have the following code:

<?php
// List of available localized versions as 'lang code' => 'url' map
$sites = array(
    "da" => "http://www.mysite.com/",
);

// Get 2 char lang code
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

// Set default language if a `$lang` version of site is not available
if (!in_array($lang, array_keys($sites)))
    $lang = 'en';

// Finally redirect to desired location
header('Location: ' . $sites[$lang]);
?>

This will redirect the user to the Danish (da) version of the site, which is the main site, if it's a Danish website client. This is excellent.

But, I want, if the user isn't Danish, but Polish, German, etc. it redirects them to the English version of the site, which is located at the subdomain 

http://en.mysite.com/

How do I implement that into the existing code? Thanks in advance! - Frederick Andersen

EDIT

A solution like;

$sites = array(
    "da" => "http://www.mysite.com/",
    "en" => "http://en.mysite.com/"
);

Doesn't work since it creates a loop error when redirecting - at least in Google Chrome.

EDIT 2

session_start();
if (isset( $_SESSION['redirect']))
{
   // do nothing / continue with rest of page
}
else
{
   $_SESSION['redirect'] = true;

// List of available localized versions as 'lang code' => 'url' map
$sites = array(
    "da" => "http://www.mysite.com/",
    "en" => "http://en.mysite.com/"
);

// Get 2 char lang code
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

// Set default language if a `$lang` version of site is not available
if (!in_array($lang, array_keys($sites)))
    $lang = 'en';

// Finally redirect to desired location
header('Location: ' . $sites[$lang]);

   exit();
}

You would need to add the default option to your array:

$sites = array(
    "da" => "http://www.mysite.com/",
    "en" => "http://en.mysite.com/"
);

Edit: If you are calling this same code in "http://en.mysite.com/" again, it will create a loop. The obvious solution would be to not call this code there, but an alternative solution would be to set a session variable to indicate that the language selection has already taken place.

To add that session variable you could do something like:

session_start();
if (isset( $_SESSION['redirect']))
{
   // do nothing / continue with rest of page
}
else
{
   $_SESSION['redirect'] = true;
   // your language selection code with header call
   exit();
}

how about this

    $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

    $sub_domain = ($lang == "da") ? "www" : "en";

    $link = "http://".$sub_domain.".mysite.com/";

    header('Location: ' . $link);
