How can i generate sitemap for my website in php

Hello, i am worried about my website developed in php for sitemaps. i tried hard but can't get it till now. please help

 

Create a PHP script (e.g. sitemap.php) that will generate the sitemap XML file:

<?php
// Define the base URL of your website
$base_url = 'https://www.example.com/';
// Start building the XML file
$xml = '<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';
// Add URLs to the sitemap
$xml .= '<url>
    <loc>' . $base_url . '</loc>
    <changefreq>daily</changefreq>
    <priority>1.0</priority>
</url>';
// Add more URLs here
// Close the XML file
$xml .= '</urlset>';
// Save the XML file
file_put_contents('sitemap.xml', $xml);
echo 'Sitemap generated successfully!';
?>

PHP:

Add more URLs to the sitemap by appending additional <url> elements to the $xml variable.
You can add dynamic URLs to the sitemap by querying your database and adding them to the sitemap XML.
Make sure to set the appropriate <changefreq> and <priority> values for each URL based on their importance and how frequently they are updated.
You can run this script periodically using a cron job to keep your sitemap up to date.
Make sure to add the generated sitemap.xml file to the root directory of your website for search engines to find it.
