title: Removing a forward-slash from the tail-end of an URL
body: <p>The code below removes "www.", etc. from the beginning of websites that are entered into a database.  It works great.</p>
  
  <p>Is there a way I could use similar code to remove a forward-slash from the tail-end of a website that is entered into the same database?  </p>
  
  <pre><code>$remove_array = array('http://www.', 'http://', 'https://', 'https://www.', 'www.');
  $site = str_replace($remove_array, "", $_POST['site']);
  </code></pre>
