What is the best way to access and manipulate objects in PHP, specifically when dealing with SimpleXMLElement instances?

When dealing with SimpleXMLElement instances in PHP, the best way to access and manipulate objects is by using the arrow operator (->) to access properties and methods of the object. This allows you to easily navigate through the XML structure and extract the data you need. 

$xml = simplexml_load_file('data.xml');

// Accessing a specific element
$element = $xml->childElement->subChildElement;

// Accessing attributes
$attribute = $element['attributeName'];

// Modifying element values
$element->subElement = 'new value';

// Adding new elements
$newElement = $xml->addChild('newElement', 'value');

// Removing elements
unset($xml->childElement->subChildElement);
