What are the differences between standard RPC and XML-RPC in PHP, and how can developers ensure compatibility with the intended interface?

Standard RPC in PHP uses a protocol that is specific to the programming language being used, while XML-RPC is a protocol that allows for communication between different programming languages and platforms. To ensure compatibility with the intended interface when using XML-RPC in PHP, developers should make sure that the data being sent and received is properly serialized and deserialized in XML format. 

// Example code snippet for ensuring compatibility with XML-RPC interface

// Create an XML-RPC client
$client = new xmlrpc_client('http://example.com/xmlrpc_server.php');

// Create an XML-RPC message
$message = new xmlrpcmsg('methodName', array(
    new xmlrpcval('param1', 'string'),
    new xmlrpcval('param2', 'int')
));

// Send the XML-RPC message and receive the response
$response = $client->send($message);

// Process the response
if ($response->faultCode()) {
    echo 'Error: ' . $response->faultString();
} else {
    echo 'Result: ' . $response->value();
}
