How can the structure of PHP and HTML code in scripts be improved for better debugging and maintenance?

The structure of PHP and HTML code in scripts can be improved for better debugging and maintenance by separating the PHP logic from the HTML presentation. This can be achieved by using PHP to generate the necessary data and then injecting it into the HTML markup using echo statements or template engines like Twig. By keeping the PHP logic separate from the HTML markup, it becomes easier to debug issues and make changes to the code in the future. 

<?php
// PHP logic to generate data
$data = [
    'name' => 'John Doe',
    'age' => 30
];

// HTML markup with PHP variables injected
?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>User Profile</title>
</head>
<body>
    <h1>Welcome, <?php echo $data['name']; ?>!</h1>
    <p>You are <?php echo $data['age']; ?> years old.</p>
</body>
</html>
