What are the best practices for structuring language arrays in PHP for multi-language websites?

When creating a multi-language website in PHP, it is best practice to structure language arrays to easily manage translations. One way to do this is by creating an associative array where each key represents a language code (e.g. 'en' for English, 'fr' for French) and the corresponding value is an array of key-value pairs for each translation. This allows for easy access to translations based on the current language selected on the website. 

// Define language arrays for English and French translations
$languages = array(
    'en' => array(
        'hello' => 'Hello',
        'welcome' => 'Welcome'
    ),
    'fr' => array(
        'hello' => 'Bonjour',
        'welcome' => 'Bienvenue'
    )
);

// Function to get translated text based on selected language
function translate($key, $lang) {
    global $languages;
    
    if(array_key_exists($lang, $languages) && array_key_exists($key, $languages[$lang])) {
        return $languages[$lang][$key];
    } else {
        return 'Translation not found';
    }
}

// Example usage
$currentLang = 'en';
echo translate('hello', $currentLang); // Output: Hello
echo translate('welcome', $currentLang); // Output: Welcome
