Regulärer Ausdruck greift nicht

[S2B]

Ich hab das Problem jetzt anders gelöst:

Code:

$accept_language = (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) ? $_SERVER['HTTP_ACCEPT_LANGUAGE'] : $_ENV['HTTP_ACCEPT_LANGUAGE'];
$accept_languages = explode(',', $accept_language);

foreach ($accept_languages as $accept_language)
{
   $accept_language = trim($accept_language);

   if (preg_match('#^[a-z]+#i', $accept_language, $match))
   {
      if (isset($match[0]) && in_array($match[0], $languages))
      {
         $user_lang = $match[0];
         break;
      }
   }
}
