How can the $page and $lang variables be efficiently queried and used to display the corresponding pages in PHP?

To efficiently query and use the $page and $lang variables to display corresponding pages in PHP, you can create an associative array that maps page names to their corresponding language versions. Then, based on the values of $page and $lang, you can retrieve the appropriate page content from the array and display it on the webpage. 

<?php
// Define an associative array mapping page names to their language versions
$pages = array(
    'home' => array(
        'en' => 'Home Page',
        'fr' => 'Page d\'accueil'
    ),
    'about' => array(
        'en' => 'About Us',
        'fr' => 'À propos de nous'
    ),
    // Add more pages and language versions as needed
);

// Retrieve the page content based on the values of $page and $lang
if (isset($pages[$page][$lang])) {
    echo $pages[$page][$lang];
} else {
    echo 'Page not found in selected language';
}
?>
