What are the potential pitfalls of trying to access XML attributes directly using array notation in PHP?

Accessing XML attributes directly using array notation in PHP can lead to potential pitfalls such as errors when the attribute does not exist, confusion with element values, and difficulty in handling multiple attributes. To avoid these issues, it's recommended to use the `getAttribute()` method provided by the SimpleXMLElement class to access XML attributes. 

// Accessing XML attributes using getAttribute() method
$xml = '<bookstore><book genre="fiction">Harry Potter</book></bookstore>';
$books = new SimpleXMLElement($xml);
$genre = $books->book->getAttribute('genre');
echo $genre; // Output: fiction
