What are the potential pitfalls of using SimpleXML for converting XML to arrays in PHP?

One potential pitfall of using SimpleXML for converting XML to arrays in PHP is that it can be cumbersome to work with and may not always produce the desired results. To avoid this, you can use the `json_encode` and `json_decode` functions to convert the SimpleXML object to a JSON string and then decode it into an associative array.

$xml = simplexml_load_string($xmlString);
$json = json_encode($xml);
$array = json_decode($json, true);
