What are the best practices for structuring PHP and HTML code in separate files for a Hangman game?

To structure PHP and HTML code in separate files for a Hangman game, it is recommended to use PHP for the backend logic and HTML for the frontend presentation. This separation of concerns makes the code more organized and easier to maintain. One approach is to create a PHP file for the backend logic (e.g., game.php) and an HTML file for the frontend display (e.g., index.html). In the PHP file, you can handle the game logic such as generating random words, checking user input, and updating the game state. In the HTML file, you can use PHP include statements to incorporate the backend logic into the frontend presentation.

// game.php (backend logic)
<?php
// Game logic code here
?>

// index.html (frontend display)
<!DOCTYPE html>
<html>
<head>
    <title>Hangman Game</title>
</head>
<body>
    <h1>Hangman Game</h1>
    <p>Guess the word:</p>
    <form method="post" action="game.php">
        <input type="text" name="guess" maxlength="1">
        <input type="submit" value="Submit">
    </form>
</body>
</html>
