Load different PHP files based on JavaScript availability

I currently have the code below (PHP)

<?php
    require_once __DIR__.'/includes/Connect.php';
    require_once __DIR__.'/includes/Nojs.php';
    require_once __DIR__.'/includes/Main.php';
    require_once __DIR__.'/includes/footer.php';
?>

I want Main.php to load only if JavaScript is enabled, and Nojs.php to load only is JavaScript is disabled.

Surrounding Nojs.php with tags does nothing (See below code)

<?php
    require_once __DIR__.'/includes/Connect.php';
?>
<noscript>
    <?php
        require_once __DIR__.'/includes/Nojs.php';
    ?>
</noscript>
<?php
    require_once __DIR__.'/includes/Main.php';
    require_once __DIR__.'/includes/footer.php';
?>

Since I know the PHP cannot access the browser as it is done server-side, is it possible to try to use HTML (Like I attempted) or other JavaScript to get it to work?
Thanks in advance.

>Solution :

Create another PHP file with no js version when first PHP loaded it will check if no js support will redirect to no js version of PHP

<noscript>
  <meta http-equiv="refresh" content="0;url=nojs-version.php">
</noscript>
