Are there any specific PHP functions or libraries that can assist with writing and formatting XML data effectively?

When working with XML data in PHP, the SimpleXML extension can be very helpful for creating and manipulating XML documents. This extension provides a simple way to interact with XML data by converting it into an object that can be easily traversed and modified. Additionally, the DOM extension can be used for more complex XML manipulation tasks. 

// Example of using SimpleXML to create and format XML data
$xml = new SimpleXMLElement('<?xml version="1.0"?><data></data>');

$xml->addChild('name', 'John Doe');
$xml->addChild('age', 30);

// Format the XML output
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());

echo $dom->saveXML();
