What are the potential pitfalls of using curl/fopen + simplexml for XML data retrieval in PHP?

One potential pitfall of using curl/fopen + simplexml for XML data retrieval in PHP is that it may not handle errors or exceptions gracefully, leading to potential security vulnerabilities or unexpected behavior. To solve this issue, it is recommended to use error handling mechanisms such as try-catch blocks to catch and handle any potential errors that may occur during the XML data retrieval process. 

try {
    $xml = simplexml_load_file('https://example.com/data.xml');
    if($xml !== false) {
        // Process the XML data here
    } else {
        throw new Exception('Error loading XML data');
    }
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
