How can the E.V.A. (Eingabe-Verarbeitung-Ausgabe) principle be applied to PHP code effectively?

The E.V.A. (Eingabe-Verarbeitung-Ausgabe) principle states that a program should clearly separate input, processing, and output operations. This helps improve code readability, maintainability, and reusability. In PHP, this can be achieved by organizing code into separate functions or classes for handling input, processing data, and displaying output. 

// Input
$input = $_POST['user_input'];

// Processing
function processInput($input) {
    // Process the input data here
    return $processedData;
}

$processedData = processInput($input);

// Output
echo $processedData;
