What are some best practices for handling SOAP responses and generating XML output in PHP applications?

When handling SOAP responses and generating XML output in PHP applications, it is important to properly parse the SOAP response and format the XML output. One best practice is to use PHP's built-in SOAP extension to handle SOAP requests and responses efficiently. Additionally, when generating XML output, consider using PHP's DOMDocument class to create well-formed XML documents. 

// Example of handling SOAP response
$client = new SoapClient("http://example.com/soap.wsdl");
$response = $client->someSoapMethod();

// Parse the SOAP response
$xml = simplexml_load_string($response);

// Example of generating XML output
$doc = new DOMDocument('1.0');
$doc->formatOutput = true;

$root = $doc->createElement('root');
$doc->appendChild($root);

$child = $doc->createElement('child', 'value');
$root->appendChild($child);

echo $doc->saveXML();
