What are some best practices for handling XML responses from external servers in PHP?

When handling XML responses from external servers in PHP, it is important to properly parse the XML data to extract the necessary information. One common approach is to use PHP's built-in SimpleXML extension, which allows for easy manipulation of XML data. Additionally, it is recommended to handle any errors that may occur during the parsing process to ensure the stability of the application. 

// Example code snippet for handling XML responses from external servers in PHP

$url = 'http://example.com/api/data.xml';
$xml = file_get_contents($url);

if ($xml) {
    $xmlData = simplexml_load_string($xml);
    
    // Extract necessary information from the XML data
    $value = $xmlData->node->value;
    
    // Handle the extracted data as needed
    echo $value;
} else {
    // Handle error when fetching XML data
    echo 'Error fetching XML data';
}
