How can trace functionality be utilized in the SoapClient class in PHP to troubleshoot issues with SOAP requests and responses?

To troubleshoot issues with SOAP requests and responses in PHP using the SoapClient class, you can enable trace functionality. This allows you to capture detailed information about the SOAP communication, including the request XML, response XML, and any errors that occur. By analyzing this trace data, you can identify the root cause of the issue and make necessary adjustments to your SOAP requests. 

// Enable trace functionality in SoapClient
$client = new SoapClient("http://example.com/soap.wsdl", array('trace' => 1));

// Make SOAP request
$response = $client->SomeSoapMethod($params);

// Output SOAP request and response
echo "Request:\n" . $client->__getLastRequest() . "\n";
echo "Response:\n" . $client->__getLastResponse() . "\n";
