How can restructuring the code to separate input validation, data processing, and output generation improve the overall quality of a PHP script?

Restructuring the code to separate input validation, data processing, and output generation can improve the overall quality of a PHP script by enhancing readability, maintainability, and reusability. It allows for easier debugging, testing, and modification of each component independently, making the code more organized and efficient. 

// Input validation
function validateInput($input) {
    // Validation logic here
    return $validatedInput;
}

// Data processing
function processData($validatedInput) {
    // Data processing logic here
    return $processedData;
}

// Output generation
function generateOutput($processedData) {
    // Output generation logic here
    return $output;
}

$input = $_POST['input'];

$validatedInput = validateInput($input);
$processedData = processData($validatedInput);
$output = generateOutput($processedData);

echo $output;
