What are the potential issues with using array functions on SimpleXMLElement objects in PHP?

When using array functions on SimpleXMLElement objects in PHP, you may encounter issues due to the fact that SimpleXMLElement objects do not behave like arrays. To solve this issue, you can convert the SimpleXMLElement object to an array using the json_encode and json_decode functions. 

// Convert SimpleXMLElement object to array
$xmlString = $xmlObject->asXML();
$jsonString = json_encode($xmlString);
$array = json_decode($jsonString, true);

// Now you can use array functions on the converted array
foreach ($array['element'] as $element) {
    // Perform operations on each element
}
