title: list of file names as dates, arrange in date order?
body: <p>I have a bunch of files on my server with file names from 'april2009' to 'march2013', a file for every month in between (plus a new file for every month from now onwards will be added).</p>
  
  <p>I tried arranging in order by using 'filemtime', but this gave a random order as they appear to have been modified all over the place.</p>
  
  <p>How can I sort through the file names and arrange in order, starting at most recent first?</p>
  
  <p>(getting the file names with php, but can use jquery or a mix for this purpose)</p>
  
  <p>thanks</p>
