title: How to implement progressive download in PHP?
body: <p>I need to provide music download service and I want to play it on Android, but it needs progressive download if I don't want to download the whole file before palying, I search it on Google but get nothing about implementation but some configuration about IIS, I'm using WAMP on my PC , what should I do?</p>
  
  <p>More precisely , How could I play the music while downloading it from my server? It seems I need implement something thing different on my server.</p>
