How can the EVA (Eingabe-Verarbeitung-Ausgabe) principle be applied to improve PHP file organization?

Issue: The EVA principle can be applied to improve PHP file organization by separating input, processing, and output into distinct sections within a PHP file. This helps in making the code more readable, maintainable, and easier to debug. 

<?php
// Input
$input_data = $_POST['data'];

// Processing
$processed_data = processData($input_data);

function processData($data) {
    // Processing logic here
    return $processed_data;
}

// Output
echo $processed_data;
?>
