title: navigate to php page and scroll
body: <p>My boss asked something very specific: a page.php that will take one argument, and display text based on that argument + when the page is displayed scroll to an anchor on the page based on that argument.</p>
  
  <p>How is that possible. 
  If I use argument ?a=1 the php can handle it, but how can the browser/javascript?
  If I use anchor #a1 the browser can handle it, but I was unable to read this with php. I used:</p>
  
  <pre><code>$_SERVER["REQUEST_URI"]
  </code></pre>
  
  <p>Any creative solutions to this problem?</p>
