What are some common challenges faced when using PHP templates for websites?

One common challenge faced when using PHP templates for websites is the potential for code duplication, leading to maintenance issues and difficulty in making updates across multiple files. To solve this, developers can use include or require statements to include common template elements in multiple files, reducing redundancy and making updates easier.

<?php
// common_header.php
?>

<!DOCTYPE html>
<html>
<head>
    <title>My Website</title>
</head>
<body>
    <header>
        <h1>Welcome to My Website</h1>
    </header>

<?php
// index.php
?>

<?php include 'common_header.php'; ?>

<main>
    <p>This is the homepage of my website.</p>
</main>

<?php
// about.php
?>

<?php include 'common_header.php'; ?>

<main>
    <p>Learn more about us on the about page.</p>
</main>

<?php
// common_footer.php
?>

    <footer>
        <p>© 2022 My Website</p>
    </footer>
</body>
</html>
