title: Stream data (such as music) using PHP (or another language)
body: <p>For years, I've been investigating how to create music streams from my computer.  I've seen programs, but anything useful I've seen is Windows only (I use a Mac).</p>
  
  <p>Eventually, I got interested in <em>how</em> streams work.  Is there any way I could create my <em>own</em> stream, possibly using socket functions in <code>PHP</code>?  Is there a <code>PHP</code> library for this?</p>
