Detect a Users Language Show something like "Language: *Your Language*"

1. Make a PHP file and insert this into it. Lets say language.php

<?php

function lixlpixel_get_env_var($Var)
{
if(empty($GLOBALS[$Var]))
{
  $GLOBALS[$Var]=(!empty($GLOBALS['_SERVER'][$Var]))?
  $GLOBALS['_SERVER'][$Var]:
  (!empty($GLOBALS['HTTP_SERVER_VARS'][$Var]))?
  $GLOBALS['HTTP_SERVER_VARS'][$Var]:'';
}
}

function lixlpixel_detect_lang()
{
// Detect HTTP_ACCEPT_LANGUAGE & HTTP_USER_AGENT.
lixlpixel_get_env_var('HTTP_ACCEPT_LANGUAGE');
lixlpixel_get_env_var('HTTP_USER_AGENT');

$_AL=strtolower($GLOBALS['HTTP_ACCEPT_LANGUAGE']);
$_UA=strtolower($GLOBALS['HTTP_USER_AGENT']);

foreach($GLOBALS['_LANG'] as $K)
{
  if(strpos($_AL, $K)===0)
   return $K;
}

foreach($GLOBALS['_LANG'] as $K)
{
  if(strpos($_AL, $K)!==false)
   return $K;
}
foreach($GLOBALS['_LANG'] as $K)
{
  if(preg_match("/[[( ]{$K}[;,_-)]/",$_UA))
   return $K;
}

return $GLOBALS['_DLANG'];
}

// Define default language.
$GLOBALS['_DLANG']='en';

// Define all available languages.
// WARNING: uncomment all available languages

$GLOBALS['_LANG'] = array(
'af', // afrikaans.
'ar', // arabic.
'bg', // bulgarian.
'ca', // catalan.
'cs', // czech.
'da', // danish.
'de', // german.
'el', // greek.
'en', // english.
'es', // spanish.
'et', // estonian.
'fi', // finnish.
'fr', // french.
'gl', // galician.
'he', // hebrew.
'hi', // hindi.
'hr', // croatian.
'hu', // hungarian.
'id', // indonesian.
'it', // italian.
'ja', // japanese.
'ko', // korean.
'ka', // georgian.
'lt', // lithuanian.
'lv', // latvian.
'ms', // malay.
'nl', // dutch.
'no', // norwegian.
'pl', // polish.
'pt', // portuguese.
'ro', // romanian.
'ru', // russian.
'sk', // slovak.
'sl', // slovenian.
'sq', // albanian.
'sr', // serbian.
'sv', // swedish.
'th', // thai.
'tr', // turkish.
'uk', // ukrainian.
'zh' // chinese.
);

echo 'Language: '.lixlpixel_detect_lang();

?>

2. Now we go to your main page and put:

<?php include('language.php'); ?>

3. That should be it.
