What are the advantages and disadvantages of using the JavaScript SDK versus the PHP SDK for implementing Facebook login on a website?

When implementing Facebook login on a website, one must decide between using the JavaScript SDK or the PHP SDK. The JavaScript SDK is easier to integrate and provides a seamless user experience, while the PHP SDK offers more control over the login process and server-side validation. The choice between the two depends on the specific requirements of the website and the desired level of customization. 

<?php
// PHP SDK implementation for Facebook login
require_once 'Facebook/autoload.php';

$fb = new Facebook\Facebook([
  'app_id' => 'your_app_id',
  'app_secret' => 'your_app_secret',
  'default_graph_version' => 'v12.0',
]);

$helper = $fb->getRedirectLoginHelper();

$permissions = ['email']; // optional permissions

$loginUrl = $helper->getLoginUrl('https://yourwebsite.com/fb-callback.php', $permissions);

echo '<a href="' . htmlspecialchars($loginUrl) . '">Log in with Facebook!</a>';
?>
