How can the EVA principle (Eingabe = Request, Verarbeitung = Parameter auslesen, validieren und damit arbeiten, Ausgabe der Ergebnisse bzw. Standardmaske) be applied to improve PHP script structure?

To improve PHP script structure using the EVA principle, we can create a clear separation between input processing, data manipulation, and output generation. This can be achieved by defining specific functions or classes for each step, making the code more modular, maintainable, and easier to debug. 

// Input processing
$request = $_POST['data'];

// Data manipulation
function process_data($input) {
    // Validate and process input data
    return $processed_data;
}

$processed_data = process_data($request);

// Output generation
function generate_output($data) {
    // Generate output based on processed data
    echo $output;
}

generate_output($processed_data);
