How to echo xml in php?

In PHP, you can echo XML by creating a string containing the XML content and then using the header() function to set the Content-Type to "text/xml" before outputting the string with echo. Here's an example:

<?php
// Set the XML content
$xml = '<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>John Doe</name>
  <age>30</age>
</root>';

// Set the Content-Type to "text/xml"
header('Content-Type: text/xml');

// Output the XML content
echo $xml;
?>

This code will output the XML content and set the Content-Type header to make sure it is interpreted as XML by the browser.
