In what scenarios would using a Message Broker be considered overkill for simple data interpretation and communication between C and PHP applications?

In scenarios where the data interpretation and communication between C and PHP applications is simple and does not require complex routing, queuing, or message processing, using a Message Broker may be considered overkill. In such cases, a direct communication method like using sockets or APIs would be more straightforward and efficient.

// PHP code snippet for simple data interpretation and communication between C and PHP applications without using a Message Broker

// C application sends data to PHP application via HTTP POST request
$data_from_c = $_POST['data'];
// Process data from C application
// Send response back to C application
