How can SoapClient and __soapCall functions be effectively used in PHP to retrieve data from external services?

SoapClient and __soapCall functions in PHP can be effectively used to retrieve data from external services by creating a SoapClient object with the WSDL file of the external service and then using the __soapCall method to make the SOAP request to the service and retrieve the data. 

// Create a new SoapClient object with the WSDL file of the external service
$client = new SoapClient("http://example.com/service.wsdl");

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

// Retrieve and use the data from the response
echo $response->data;
