title: Disable a PHP website temporarily
body: <p>I have a PHP website that I own. I want to temporarily disable the website while I am making my changes (there are a lot to do). I tried to rename the <code>index.php</code> file but the end-user can always navigate to a page by typing the URL ( or if he had bookmarked the page ). Is there a way I can disable the whole website temporarily?</p>
  
  <p>Edit : This accepted answers work for an apache web server. What I am using presently is IIS6 ( and not IIS7 where the same rewrite can be done in web.config file ). Is there a way around for this problem in IIS6?</p>
