What are some best practices for manipulating XML files in PHP for data transformation?

When manipulating XML files in PHP for data transformation, it is important to use built-in functions like SimpleXML or DOMDocument for easy parsing and manipulation. Best practices include loading the XML file, making changes to the data structure, and saving the modified XML back to a file. 

// Load the XML file
$xml = simplexml_load_file('data.xml');

// Make changes to the XML data structure
$xml->book[0]->title = 'New Title';
$xml->book[0]->author = 'New Author';

// Save the modified XML back to a file
$xml->asXML('updated_data.xml');
