How can JavaScript be integrated with PHP page redirection to improve user experience on a website?

When integrating JavaScript with PHP page redirection, you can use JavaScript to handle the redirection process on the client-side, providing a smoother and more interactive user experience. By combining the server-side capabilities of PHP with the client-side interactivity of JavaScript, you can create dynamic and responsive page redirections based on user actions or conditions.

<?php
  // PHP code to check for a specific condition
  $condition = true;

  if ($condition) {
    echo '<script>window.location.href = "newpage.php";</script>';
  }
?>
