title: Display an image according to the moon phase
body: <p>I'd like to know if it's possible to calculate the current moon phase or get it from somewhere (www, rss, I don't know..) in PHP.</p>
  
  <p>Basically I need to display an image in a website depending on the current moon phase.</p>
  
  <p>I found this: <a href="http://jivebay.com/2010/01/04/calculating-the-moon-phase-part-2/" rel="nofollow">http://jivebay.com/2010/01/04/calculating-the-moon-phase-part-2/</a> , however, the author says it's not 100% accurate.</p>
  
  <p>Any ideas ? thanks!</p>
