When dealing with PHP templates, how can one ensure that PHP code within the templates does not interfere with XML validation or parsing?

When dealing with PHP templates, one way to ensure that PHP code does not interfere with XML validation or parsing is to use PHP's output buffering functions to capture the output of the PHP code and then insert it into the XML template as a variable. This way, the PHP code is executed separately from the XML parsing process, preventing any conflicts. 

<?php
ob_start();
// PHP code that generates content
$content = ob_get_clean();
$xml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<root>
    <data>{$content}</data>
</root>
XML;
echo $xml;
?>
