What are the potential pitfalls of combining PHP and HTML for player integration?

One potential pitfall of combining PHP and HTML for player integration is the risk of mixing logic and presentation, leading to messy and hard-to-maintain code. To solve this issue, it is recommended to separate the PHP logic from the HTML markup by using a template engine like Twig or Blade. This way, the PHP code can handle the backend logic while the HTML templates handle the frontend presentation.

<?php
// PHP logic
$playerName = "John Doe";
$playerScore = 100;

// HTML markup using a template engine
echo $twig->render('player_template.html', ['playerName' => $playerName, 'playerScore' => $playerScore]);
?>
