What is the best practice for encoding SOAP responses in XML in PHP?

When encoding SOAP responses in XML in PHP, it is best practice to use the built-in SoapClient class provided by PHP. This class handles the encoding of SOAP requests and responses automatically, making it easier to work with SOAP services.

// Create a new SoapClient instance
$client = new SoapClient("http://example.com/soap.wsdl");

// Make a SOAP request
$response = $client->__soapCall("methodName", $params);

// Output the SOAP response
echo $client->__getLastResponse();
