How can PHP handle multiple languages and regions for a website?

To handle multiple languages and regions for a website in PHP, you can use language files with translations for different languages. These language files can be stored in separate directories or files based on the language or region. By using PHP's `gettext` extension or creating your own language switching mechanism, you can dynamically load the appropriate language file based on the user's preferences. 

// Example code snippet for handling multiple languages in PHP

// Set the default language
$language = 'en_US';

// Check if the user has selected a different language
if(isset($_GET['lang'])) {
    $language = $_GET['lang'];
}

// Load the appropriate language file based on the selected language
require_once('languages/'.$language.'.php');

// Usage example: echo _('Hello World!'); // Output will be translated based on the selected language
