How can XML data be effectively loaded and processed in PHP to populate arrays for comparison and sorting?

To effectively load and process XML data in PHP to populate arrays for comparison and sorting, you can use the SimpleXMLElement class to parse the XML data and convert it into an array. Once the XML data is converted into an array, you can then perform comparisons and sorting operations on the data as needed. 

$xmlData = '<data>
            <item>
                <name>Apple</name>
                <price>1.99</price>
            </item>
            <item>
                <name>Orange</name>
                <price>0.99</price>
            </item>
            </data>';

$xml = new SimpleXMLElement($xmlData);
$json = json_encode($xml);
$array = json_decode($json,TRUE);

// Now $array contains the XML data in array format
// Perform comparison and sorting operations on $array as needed
