Question

I need a way to include a php file based on the language in the URL. Right now this script is working, but when I have 10 or 20 languages I would like some sort of shorter script, that still contains the same information. The thing is, if the ‘lg’ in the URL is changed to a language that doesn’t exist, I would like to use the english language.

$langue=$_GET['lg'];
if ($langue == "da")
{ include"da.php";}
elseif ($langue == "de")
{ include"de.php";}
elseif ($langue == "en")
{ include"en.php";}
elseif ($langue == "es")
{ include"es.php";}
else { include"en.php";}

Anybody who can shorten this one?

Answer 1

if (empty($_GET['lg'])) {
  $lang = "en";
} else {
  $lang = $_GET['lg'];
}
if ( !preg_match('~^[a-z]{2}$~',$lang) ) {
  header('HTTP/1.1 403 Forbidden'); 
  exit;
}
$langfile = "$lang.php";
if (!is_readable($langfile)) {
  $lang     = "en";
  $langfile = 'en.php';
}
include $langfile;
