Is it necessary to have a deep understanding of classes and objects in PHP before attempting to create and save XML files on a server?

It is not necessary to have a deep understanding of classes and objects in PHP to create and save XML files on a server. You can use built-in PHP functions like `simplexml_load_string()` and `file_put_contents()` to easily create and save XML files without the need for complex object-oriented programming.

$xml = new SimpleXMLElement('<root></root>'); // Create a new XML element
$xml->addChild('name', 'John Doe'); // Add a child element
$xml->addChild('email', 'john.doe@example.com'); // Add another child element

file_put_contents('data.xml', $xml->asXML()); // Save the XML to a file
