How can SOAP or other web service protocols be used as a more secure alternative to including external code in PHP scripts?

Including external code in PHP scripts can pose security risks such as code injection attacks. To address this, SOAP or other web service protocols can be used as a more secure alternative. By using web services, the PHP script can communicate with external services without directly executing their code, reducing the risk of vulnerabilities.

// Example of using SOAP to communicate with an external service securely

// Create a new SOAP client
$client = new SoapClient("https://example.com/webservice");

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

// Process the response from the SOAP service
echo $response;
