What are some common issues that may cause Google's internal validator to flag errors in PHP-generated sitemaps?

One common issue that may cause Google's internal validator to flag errors in PHP-generated sitemaps is incorrect formatting of the XML file. Ensure that the XML file is properly structured with the correct tags and attributes. Another issue could be missing or incorrect URL elements within the sitemap. Make sure that each URL entry includes the required elements such as loc, lastmod, and changefreq. 

<?php
// Example of correctly formatting a sitemap XML file
header('Content-type: text/xml');
echo '<?xml version="1.0" encoding="UTF-8"?>';
echo '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';
echo '<url>';
echo '<loc>https://www.example.com/page1</loc>';
echo '<lastmod>2022-01-01</lastmod>';
echo '<changefreq>monthly</changefreq>';
echo '</url>';
echo '</urlset>';
?>
