How can you use simpleXML to determine the name of an element in PHP?

To determine the name of an element using SimpleXML in PHP, you can use the `getName()` method provided by SimpleXML. This method returns the name of the current element being processed. By calling `getName()` on a SimpleXML object, you can easily retrieve the element's name.

$xml = simplexml_load_string($xmlString);

foreach ($xml->children() as $child) {
    echo $child->getName() . "<br>";
}
