What are some common methods for building a multilingual website in PHP?

Building a multilingual website in PHP involves creating language files for each supported language and implementing a mechanism to switch between these languages based on user preferences or browser settings. One common method is to use arrays or key-value pairs to store translations for different languages, and then dynamically load the appropriate language file based on the user's selection. 

// Define language files for different languages
$language_files = array(
    'en' => 'english.php',
    'fr' => 'french.php',
    'es' => 'spanish.php'
);

// Get the selected language from user preferences or browser settings
$selected_language = isset($_GET['lang']) ? $_GET['lang'] : 'en';

// Load the appropriate language file
if(array_key_exists($selected_language, $language_files)) {
    include($language_files[$selected_language]);
} else {
    include('english.php'); // Default to English if selected language is not supported
}
