What are the advantages and disadvantages of using the classmap option in SoapClient for transforming SOAP response data in PHP?

The classmap option in SoapClient allows for mapping complex SOAP response data to PHP objects, making it easier to work with the data in a structured manner. This can help in improving code readability and maintainability. However, using classmap can also lead to increased memory usage and performance overhead, especially when dealing with large datasets.

// Example of using classmap option in SoapClient to transform SOAP response data

$options = array(
    'classmap' => array(
        'ResponseObject' => ResponseObject::class,
        'NestedObject' => NestedObject::class
    )
);

$client = new SoapClient('http://example.com/wsdl', $options);

$response = $client->someSoapMethod();

// Now $response will be an instance of ResponseObject or NestedObject based on the SOAP response structure
