What are some best practices for implementing multi-language websites in PHP?

When implementing multi-language websites in PHP, it is best practice to use language files to store translations for each language. This allows for easy management and updating of translations. Additionally, using language constants or functions to retrieve translations ensures consistency across the website. 

// Define language files for each language
$language = 'en';
$language_file = 'lang/' . $language . '.php';

// Include language file
if (file_exists($language_file)) {
    include($language_file);
}

// Function to retrieve translation
function translate($key) {
    global $lang;
    return isset($lang[$key]) ? $lang[$key] : $key;
}

// Example of translating a string
echo translate('welcome_message');
