PHP is a popular scripting language used for web development, and it has built-in support for consuming and creating SOAP web services.

SOAP (Simple Object Access Protocol) is a protocol for exchanging structured information in web services using XML. It allows different applications to communicate with each other over a network.

To consume a SOAP web service in PHP, you can use the built-in SOAP extension. Here’s an example of how to consume a SOAP web service:

// Create a new SOAP client
$client = new SoapClient(‘’);

// Call a method on the SOAP service
$response = $client->methodName($param1, $param2);

// Access the response data
$result = $response->methodNameResult;

In this example, `` is the URL of the SOAP WSDL (Web Services Description Language) file.

To create a SOAP web service in PHP, you can use the built-in SOAP extension as well. Here’s an example of how to create a SOAP web service:

// Define a class for your SOAP service
class MyService {
public function methodName($param1, $param2) {
// Process the parameters and return a response
return $param1 + $param2;

// Create a new SOAP server
$server = new SoapServer(‘’);

// Register your SOAP service with the server

// Handle the SOAP request

In this example, `` is the URL where the WSDL file for your SOAP service will be available. The `MyService` class defines the methods that can be called on the SOAP service.

SOAP web services can also have complex data structures and support for different data types. You can define these in the WSDL file or use the built-in SOAP types in PHP. Additionally, you can use SOAP headers to provide security or additional information in your SOAP requests and responses.

Overall, PHP provides a straightforward way to consume and create SOAP web services using the built-in SOAP extension.
