title: How to push to iphone / android phones via php
body: <p>How can I use a php script to push to an iphone or android phone?</p>
  
  <p>What I am thinking right now is to have a php script that will run every 15 minutes on a web server, check  if case x is satisfied, if not push a notification to the phone.</p>
  
  <p>How can this be accomplished if its even possible?  If not what approach should I take to achieving this? Any links or break downs would be greatly appreciated.</p>
