How can the separation of concerns principle (EVA - Input, Processing, Output) be applied to PHP scripts to improve code structure and maintainability?

Separating concerns in PHP scripts can improve code structure and maintainability by dividing the code into distinct sections for input, processing, and output. This helps to organize the code logically, making it easier to understand, maintain, and debug. 

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

// Processing
$processedData = processData($input);

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

// Output
echo $processedData;
