To echo XML in PHP, you can use the header() function to set the content type to text/xml and then use the echo or print function to output the XML content. Here is an example:

<?php
// Set the content type to XML
header('Content-type: text/xml');

// Create XML content
$xml = '<?xml version="1.0" encoding="UTF-8"?>
<root>
  <title>Hello World</title>
  <message>Welcome to the world of XML</message>
</root>';

// Output XML content
echo $xml;
?>

This code will output the XML content with the appropriate content type header. You can customize the XML content based on your requirements.
