What are common methods for implementing multi-language support in PHP websites?

Implementing multi-language support in PHP websites can be achieved by using language files that contain translations for different languages. These language files can be loaded based on the user's language preference, allowing the website to display content in the selected language. 

// 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 loading language file based on user's language preference
$userLang = isset($_GET['lang']) ? $_GET['lang'] : 'en'; // Default to English if no language preference set
loadLanguageFile($userLang);

// Usage example: echo $lang['hello']; // Display translated "hello" message
