In what ways can HTML experience enhance the development of a PHP-based forum, especially when it comes to user authentication and authorization?

HTML experience can enhance the development of a PHP-based forum by allowing for a more user-friendly interface for user authentication and authorization. HTML can be used to create visually appealing login forms, registration forms, and user profile pages. Additionally, HTML can be used to implement client-side validation for input fields, improving the user experience and reducing server-side processing.

<?php
// HTML code for a simple login form
echo '<form action="login.php" method="post">';
echo 'Username: <input type="text" name="username"><br>';
echo 'Password: <input type="password" name="password"><br>';
echo '<input type="submit" value="Login">';
echo '</form>';
?>
