What are some recommended approaches for automating processes with SOAP services in a PHP program?

When automating processes with SOAP services in a PHP program, one recommended approach is to use the built-in SOAP extension in PHP. This extension allows you to easily create SOAP clients and make requests to SOAP services. Another approach is to use a library like NuSOAP or Zend_Soap_Client, which provide additional features and flexibility when working with SOAP services.

// Using the built-in SOAP extension in PHP
$client = new SoapClient("http://example.com/soap.wsdl");
$response = $client->__soapCall("methodName", array($params));

// Using NuSOAP library
require_once('lib/nusoap.php');
$client = new nusoap_client("http://example.com/soap.wsdl", 'wsdl');
$response = $client->call("methodName", array($params));

// Using Zend_Soap_Client
require_once('Zend/Soap/Client.php');
$client = new Zend_Soap_Client("http://example.com/soap.wsdl");
$response = $client->methodName($params);
