What are the best practices for structuring PHP code to efficiently handle multilingual content and translations within a web application?

To efficiently handle multilingual content and translations within a web application, it is best to use language files to store all the translations in separate files for each language. This allows for easy management and updating of translations without modifying the code. Additionally, using a function to retrieve the translated text based on the selected language can help streamline the process. 

// Function to retrieve translated text based on selected language
function translate($key, $language = 'en') {
    $translations = include 'languages/' . $language . '.php';
    return isset($translations[$key]) ? $translations[$key] : $key;
}

// Example of language file structure (languages/en.php)
return [
    'welcome_message' => 'Welcome to our website',
    'about_us' => 'About Us',
    'contact_us' => 'Contact Us'
];

// Usage example
echo translate('welcome_message', 'fr'); // Output: 'Bienvenue sur notre site web'
