What are the key differences between client-side and server-side SOAP implementation in PHP?
When implementing SOAP in PHP, the key difference between client-side and server-side implementation lies in the roles they play. Client-side SOAP implementation involves sending SOAP requests to a server and processing the responses, while server-side SOAP implementation involves receiving SOAP requests from clients and generating appropriate responses. For client-side SOAP implementation in PHP:
<?php
// Create a new SOAP client
$client = new SoapClient("http://example.com/soap_server.php?wsdl");
// Call a remote SOAP function
$response = $client->__soapCall("remoteFunction", array($param1, $param2));
// Process the response
echo $response;
?>
