What are the key components required in a PHP script to handle SOAP requests and responses effectively?

To handle SOAP requests and responses effectively in a PHP script, you need to use the SOAP extension provided by PHP. Key components required include creating a SOAP client object, setting the SOAP server URL, defining the SOAP request parameters, calling the SOAP method, and processing the SOAP response.

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

// Define the SOAP request parameters
$params = array('param1' => 'value1', 'param2' => 'value2');

// Call the SOAP method
$response = $client->__soapCall('methodName', array($params));

// Process the SOAP response
var_dump($response);
