What best practices should PHP developers follow when working with arrays and objects to create XML output?

When working with arrays and objects to create XML output in PHP, it is important to properly format the data structure to ensure valid XML is generated. One common approach is to use the SimpleXMLElement class to easily create XML nodes from arrays and objects. This class provides methods to add child elements, attributes, and text data to the XML output. 

// Sample PHP code snippet to create XML output from an array using SimpleXMLElement

$data = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
];

$xml = new SimpleXMLElement('<root/>');
array_walk_recursive($data, array ($xml, 'addChild'));

echo $xml->asXML();
