How can a multi-language website be implemented efficiently using PHP?

To implement a multi-language website efficiently using PHP, you can use language files to store translations for different languages. Create separate language files for each language, and then dynamically load the appropriate language file based on the user's language preference. You can then use PHP functions to retrieve the translated text from the language file and display it on the website. 

// Function to load language file based on user's language preference
function loadLanguageFile($lang) {
    $langFile = 'languages/' . $lang . '.php';
    
    if(file_exists($langFile)) {
        include($langFile);
    } else {
        include('languages/english.php'); // Default to English if language file not found
    }
}

// Example of retrieving translated text from language file
loadLanguageFile('spanish');
echo $lang['welcome_message']; // Display translated text for 'welcome_message'
