Are there any common pitfalls to avoid when integrating language files with Smarty in PHP?

One common pitfall to avoid when integrating language files with Smarty in PHP is not properly escaping the translated text before displaying it. This can lead to security vulnerabilities such as cross-site scripting (XSS) attacks. To prevent this, always use Smarty's escape modifier when outputting translated text in your templates.

// Example of integrating language files with Smarty in PHP while properly escaping translated text

// Load language file
$language = new Language();
$translations = $language->loadTranslations('en');

// Assign translations to Smarty template
$smarty->assign('translations', $translations);

// In your Smarty template, use the escape modifier when outputting translated text
{$translations.greeting|escape}
