// Define the English and French translations of the string $text = array( 'en_EN' => 'Welcome to our website!', 'fr_FR' => 'Bienvenue sur notre site web!' ); // Get the current language code from the user's session $lang = $_SESSION['lang']; // Display the appropriate translation of the string echo JText::alt($text, $lang);In this example, the `$text` array contains the English and French translations of a welcome message. The `JText::alt()` method is then used to retrieve the appropriate translation based on the `$lang` variable, which is determined by the user's language preference stored in the session. Overall, JText is a useful package library for managing multilingual text strings in PHP web applications, with features like JText Alt allowing developers to easily handle alternative translations.
