When dealing with XML data in PHP, how can one determine whether to use an array or an object to access specific elements?

When dealing with XML data in PHP, one can determine whether to use an array or an object to access specific elements based on the structure of the XML data. If the XML data has nested elements and attributes, it is recommended to use an object to access the elements as objects provide a more structured way to access the data. On the other hand, if the XML data is more flat and consists mainly of key-value pairs, using an array might be more suitable. 

// Example of accessing XML data using SimpleXML as an object
$xml = simplexml_load_string($xmlString);
echo $xml->elementName;

// Example of accessing XML data using SimpleXML as an array
$xml = simplexml_load_string($xmlString, 'SimpleXMLElement', LIBXML_NOCDATA);
echo $xml['elementName'];
