Question

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.index.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');
