title: Files download queue on php
body: <p>I need to implement some kind of files download queue. I plan to use wget for file download.</p>
  
  <p>My question is - how to get information from wget when the file has been downloaded ?</p>
  
  <p>Is it possible to setup callback or trigger on wget in order to do that ?</p>
  
  <p>Also, you are welcome to recommend some other stuff instead of wget in order to use it for files download.</p>
  
  <p>Thanks in advance,
  Alex</p>
