What are some common methods for implementing multilingual functionality on a PHP website?

Implementing multilingual functionality on a PHP website can be achieved by using language files, where each language has its own file containing key-value pairs for translations. By detecting the user's language preference and loading the corresponding language file, the website can display content in the user's preferred language. 

// Detect user's language preference
$user_language = $_SERVER['HTTP_ACCEPT_LANGUAGE'];

// Load language file based on user's preference
if(strpos($user_language, 'fr') !== false) {
    include 'languages/fr.php'; // French language file
} else {
    include 'languages/en.php'; // Default to English language file
}

// Example language file (fr.php)
$lang['welcome'] = 'Bienvenue';
$lang['hello'] = 'Bonjour';

// Display translated content
echo $lang['welcome'];
echo $lang['hello'];
