Is it possible to have my dynamic page saved daily by Google?

To have your dynamic page saved daily by Google, you can create a sitemap.xml file that includes the URLs of your dynamic pages. This file can be submitted to Google Search Console to ensure that Google crawls and indexes your dynamic pages regularly.

<?php
// Create a sitemap.xml file with the URLs of your dynamic pages
$sitemap = '<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/dynamic-page-1</loc>
    <changefreq>daily</changefreq>
  </url>
  <url>
    <loc>https://example.com/dynamic-page-2</loc>
    <changefreq>daily</changefreq>
  </url>
</urlset>';

// Save the sitemap.xml file
file_put_contents('sitemap.xml', $sitemap);

// Submit the sitemap.xml file to Google Search Console
// This can be done manually through the Google Search Console interface
?>
