What are the best practices for incorporating multilingual support in PHP scripts for user interface elements like buttons?

When incorporating multilingual support in PHP scripts for user interface elements like buttons, it is best to use language files to store translations for each language. This allows for easy maintenance and updates of translations without modifying the code. To implement this, you can create separate language files for each supported language and then load the appropriate language file based on the user's language preference. 

// Function to load language file
function loadLanguageFile($lang) {
    $langFile = "lang/{$lang}.php";
    if (file_exists($langFile)) {
        include $langFile;
    }
}

// Example of language file for English
$lang['button_submit'] = "Submit";
$lang['button_cancel'] = "Cancel";

// Load language file based on user's language preference
$userLanguage = "en"; // Example language preference
loadLanguageFile($userLanguage);

// Usage of translated strings in UI elements
echo '<button>' . $lang['button_submit'] . '</button>';
echo '<button>' . $lang['button_cancel'] . '</button>';
