Using the PHP HTTP_ACCEPT_LANGUAGE server variable

Question

I created a PHP script that checks the HTTP_ACCEPT_LANGUAGE and loads the website using the appropriate language from the 1st two characters:

          $http         


        

Answer 1

In the end I went with this solution:

if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
  preg_match_all('/([a-z]{1,8}(-[a-z]{1,8})?)\s*(;\s*q\s*=\s*(1|0\.[0-9]+))?/i', $_SERVER['HTTP_ACCEPT_LANGUAGE'], $lang_parse);
  if (count($lang_parse[1])){
    $langs = array_combine($lang_parse[1], $lang_parse[4]);
    foreach ($langs as $lang => $val){
      if ($val === '') $langs[$lang] = 1;
    }
    arsort($langs, SORT_NUMERIC);
  }
  foreach ($langs as $lang => $val){
    if (strpos($lang,'en')===0){
      $language = 'english';
      break;
    } else if (strpos($lang,'es')===0){
      $language = 'spanish';
    }
  }
}
