title: $_GET difference when calling URL with or without anchor
body: <p>Why does $_GET deliver different results if I call an URL with an anchor compared to without?</p>
  
  <p>example:</p>
  
  <pre><code>https://www.myurl.com/#anchor?param1=x&amp;param2=y
  </code></pre>
  
  <p>if I read the GET params, REQUEST, $_SERVER['QUERY_STRING'], parse_url($url, PHP_URL_QUERY)
  all are emtpy</p>
  
  <p>but with </p>
  
  <pre><code>https://www.myurl.com/?param1=x&amp;param2=y
  </code></pre>
  
  <p>everything works as expected.</p>
  
  <p>Can anyone explain me this please?</p>
