    WordPress Titles
    To create the file name portion of a URL the same way that WordPress does use this:

    <?php
  $new_url = sanitize_title('This Long Title is what My Post or Page might be');
  echo $new_url;
?>

    It should return a formatted value, the output would be this:

    this-long-title-is-what-my-post-or-page-might-be
