What are the potential pitfalls of including PHP elements in an HTML file and parsing them in a separate PHP file?

Including PHP elements in an HTML file can make the code harder to read and maintain. It is better to separate the PHP logic into a separate PHP file and parse it using include or require statements in the HTML file. This approach helps to keep the code organized and makes it easier to debug and modify in the future. 

// Separate PHP logic into a separate file
// index.php
<!DOCTYPE html>
<html>
<head>
    <title>PHP Include Example</title>
</head>
<body>
    <header>
        <?php include 'header.php'; ?>
    </header>
    <main>
        <p>Welcome to our website!</p>
    </main>
    <footer>
        <?php include 'footer.php'; ?>
    </footer>
</body>
</html>

// header.php
<h1>Welcome to our website</h1>
