How can PHP developers ensure a more structured and readable output when working with complex XML data structures like the one provided in the example?

When working with complex XML data structures, PHP developers can ensure a more structured and readable output by using XML parsing functions such as SimpleXML or DOMDocument. These functions allow developers to easily navigate through the XML data and extract the necessary information in a more organized manner. By properly formatting the output and using appropriate indentation, the XML data can be presented in a clear and understandable way. 

<?php
$xmlString = '<data>
    <person>
        <name>John Doe</name>
        <age>30</age>
    </person>
    <person>
        <name>Jane Smith</name>
        <age>25</age>
    </person>
</data>';

$xml = simplexml_load_string($xmlString);

echo "<pre>";
print_r($xml);
echo "</pre>";
?>
