sitemap.xml generator UPDATED

A while back I created a script to scan your permalinks database and generate an xml sitemap for you. I have done a few revisions with the help of claude.ai to make it more useful and you can run it from your own site to generate a sitemap for your customers (that's if your customers site allows access to the database), if not you can upload it to theirs.
This script will generate a sitemap.xml using permalinks from the cmsb__permalinks table where old=0. After generation, you can choose to replace the existing sitemap.xml in your root directory, download it to your computer, or view it in your browser.
Note it assumes you have use cmsb as your database table prefix.
<?php
// Start session to store sitemap content
session_start();
// Handle actions
if (isset($_GET['action']) && isset($_SESSION['sitemap_content'])) {
switch ($_GET['action']) {
case 'download':
header('Content-Type: application/xml');
header('Content-Disposition: attachment; filename="sitemap.xml"');
header('Content-Length: ' . strlen($_SESSION['sitemap_content']));
echo $_SESSION['sitemap_content'];
exit;
case 'view':
header('Content-Type: text/plain');
echo $_SESSION['sitemap_content'];
exit;
case 'replace':
if (file_put_contents($_SERVER['DOCUMENT_ROOT'] . '/sitemap.xml', $_SESSION['sitemap_content']) === false) {
$error = 'Failed to write sitemap.xml to root directory';
} else {
$replace_success = 'Sitemap.xml has been successfully replaced in the root directory!';
}
break;
}
}
// Function to generate the sitemap XML
function generateSitemap($baseUrl, $urls) {
$sitemap = '<?xml version="1.0" encoding="UTF-8"?>' . PHP_EOL;
$sitemap .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">' . PHP_EOL;
foreach ($urls as $url) {
// Ensure there are no leading/trailing slashes in the URL
$trimmedUrl = trim($url, '/');
$fullUrl = $baseUrl . '/' . $trimmedUrl . '/';
$sitemap .= ' <url>' . PHP_EOL;
$sitemap .= ' <loc>' . htmlspecialchars($fullUrl) . '</loc>' . PHP_EOL;

return $sitemap;

$dbHost = $_POST['db_host'];

$error = "Please fill in all required fields.";

$dsn = "mysql:host=$dbHost;dbname=$dbName";
$options = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
];
try {
$pdo = new PDO($dsn, $dbUsername, $dbPassword, $options);
// Fetch URLs from the database
$urls = [];
$query = $pdo->query('SELECT permalink FROM cmsb__permalinks WHERE old=0');
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
