Creating multilanguage homepage

so im making homepage with three languages. I am using switch method, here is code -

  public function languages()
{
if (isset($_GET['lang']) && $_GET['lang'] != '')
{
  $_SESSION['lang'] = $_GET['lang'];
}
else
{
  $_SESSION['lang'] = 'en_EN';
}
switch($_SESSION['lang'])
{
  case 'en_EN': require_once('language/lang.eng.php');break;
  case 'lv_LV': require_once('language/lang.lv.php');break;
  case 'ru_RU': require_once('language/lang.ru.php');break;
  default: require_once('language/lang.eng.php');
}
}

public function translate($txt)
{
  global $text;
  return $text[$txt];
}

and it should display in index.php file like this -

<?php $index->translate('search'); ?>

but the problem is that it shows no errors, no notices, no warnings and no translated or default text. I included function languages() , maybe you can help me with this problem?

EDIT: im calling $language at start of index.php file - <?php require_once('class.ind开发者_JS百科ex.php'); $index = new index; $index->languages(); ?> and $text is defined in lang.eng.php; lang.lv.php and lang.ru.php file.

Since you're using a class, I think it's better to use properties instead of globals, it will be easier in future mantainance. Create a class variable holding $text and use that

class Index {

  var $text;

  public function languages()
  {
    require(".....");

    $this->text = $text;
  }

  public function translate($txt)
  {
    if(isset($this->text[$txt]))
    {
      return $this->text[$txt];
    }
    else
    {
     return "no translation";
    }
  }

}

$index = new Index;
$index->languages();
echo $index->translate('search'); 

type

<?php echo $index->translate('search'); ?>

Check first whether the session is initialized or not and also place the languages() function call before the translate so that it loads the language prior to translation and also put error_reporting(E_ALL) at top so that any error suppresion will be be removed and also put echo the returned result of translate statement
