What are the benefits of separating PHP logic for data processing and HTML output to improve code readability and maintainability?

Separating PHP logic for data processing and HTML output improves code readability and maintainability by keeping the presentation layer (HTML) separate from the business logic. This separation allows for easier debugging, testing, and modification of each part independently. It also promotes better organization and reusability of code. 

<?php
// Data processing logic
$data = fetchDataFromDatabase();

// HTML output
?>
<!DOCTYPE html>
<html>
<head>
    <title>PHP Separation Example</title>
</head>
<body>
    <h1>Data Processing and HTML Output Separated</h1>
    <p><?php echo $data; ?></p>
</body>
</html>
