How can PHP developers ensure clear definition of elements in SOAP requests?

To ensure clear definition of elements in SOAP requests, PHP developers can use the `SoapVar` class to explicitly define the data types and structures of the elements being sent in the request. By creating `SoapVar` objects for each element, developers can ensure that the SOAP request is well-defined and easily understood by both the client and server. 

// Define the element with SoapVar
$element = new SoapVar('value', XSD_STRING, 'string', 'http://www.w3.org/2001/XMLSchema');

// Add the element to the SOAP request
$request = new stdClass();
$request->element = $element;

// Send the SOAP request
$client = new SoapClient('http://example.com/service.wsdl');
$response = $client->__soapCall('methodName', [$request]);
