What are some best practices for handling SOAP requests and responses in PHP?

When handling SOAP requests and responses in PHP, it is important to properly parse the incoming SOAP request and format the response according to the SOAP standards. One common best practice is to use PHP's built-in SoapClient class to handle SOAP requests and responses efficiently.

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

// Make a SOAP request
$response = $client->__soapCall("exampleMethod", [$requestParams]);

// Format the SOAP response
$soapResponse = new SoapVar($response, SOAP_ENC_OBJECT);

// Send the SOAP response
header('Content-Type: text/xml');
echo $soapResponse;
