What are some best practices for maintaining code aesthetics in dynamically generated PHP code?

Maintaining code aesthetics in dynamically generated PHP code can be challenging due to the mix of HTML and PHP syntax. One way to improve readability is to separate PHP logic from HTML markup by using PHP alternate syntax or template engines like Twig. Additionally, using proper indentation, comments, and consistent naming conventions can also help in keeping the code clean and organized.

<?php

// Example of using PHP alternate syntax to separate PHP logic from HTML markup
?>
<!DOCTYPE html>
<html>
<head>
    <title>Dynamic PHP Code</title>
</head>
<body>
    <h1>Welcome, <?php echo $username; ?>!</h1>
    <p>Your email address is: <?php echo $email; ?></p>
</body>
</html>
