title: Remove & and Whitespace in URL with preg_replace
body: <p>I am trying to remove Whitespaces and &amp; in a URL and replace it with a -. So far the following works:</p>
  
  <pre><code>preg_replace('/\s+/', '-', $page-&gt;label) // whitepace gets replaced with -    
  preg_replace('/\&amp;/', '-', $page-&gt;label) // &amp; gets replaced with - 
  </code></pre>
  
  <p>I would like to have this in one line, but I am not able to combine the 2. Can anyone help?
  Thank you very much in advance.   </p>
