What are the advantages of implementing routing and dispatching for language selection in PHP?

When building a multilingual website in PHP, it is important to implement routing and dispatching for language selection to ensure that users can easily switch between different languages. This allows for a seamless user experience and helps in maintaining a consistent design across all language versions of the website. 

// Sample PHP code snippet for implementing routing and dispatching for language selection

// Get the current language from the URL parameter or session
$language = isset($_GET['lang']) ? $_GET['lang'] : 'en';

// Define an array of supported languages
$supportedLanguages = ['en', 'es', 'fr'];

// Check if the selected language is supported, if not, default to English
if (!in_array($language, $supportedLanguages)) {
    $language = 'en';
}

// Include language-specific files based on the selected language
require_once "lang/{$language}.php";

// Use the language variables in your PHP code
echo $lang['welcome_message'];
